Ingredients for bean and lentil salad

Fifteen minutes of prep transforms these simple ingredients into a protein-packed, restaurant-worthy salad.

The lentils are the star here—French green lentils hold their shape beautifully and add that satisfying meaty texture. Grab the dried kind from Whole Foods or Trader Joe's (their bulk section is perfect), but any dried lentils will work. Pre-cooking them for 15 minutes in boiling water with a pinch of salt is a game-changer—it softens them just enough to be creamy without turning mushy. For the beans, low-sodium canned varieties are a must unless you're okay with salty flavor. Drain and rinse them thoroughly to cut any residual sodium. The red bell pepper should be vibrant, not waxy—Heirloom varieties from the farmers market have the best flavor, but store-bought works too.

No fresh herbs? Dried parsley and dill at half the amount will get you close, but fresh is ideal for that bright, herby punch. Running short on olive oil? Avocado oil works perfectly—it's neutral and high-heat stable, though it lacks that fruity depth. For the dressing, raw apple cider vinegar adds complexity that regular vinegar can't match. Skip the maple syrup if you're watching sugar? Agave nectar or date syrup are great swaps. The avocado is optional but adds incredible creaminess— Hass variety is best when slightly underripe for longer shelf life. If you're prepping ahead, hold off on adding the avocado until serving to prevent browning.

This salad keeps beautifully for 4-5 days in the fridge, with the dressing staying vibrant if stored separately. For meal prep, portion into glass containers with tight lids—they keep everything crisp. The dressing can be made up to 1 week ahead and stored in a sealed jar. When ready to serve, give everything a good toss and adjust seasoning with a pinch of salt or extra lemon juice. The flavors actually improve after sitting for an hour, so let it chill while you prep the rest of your meal. Leftovers? It reheats surprisingly well—just warm gently with a splash of water to revive the textures.

Step-by-step instructions for protein-packed bean and lentil salad

Here's how to assemble this vibrant, protein-rich salad with crisp textures and bold flavors.

Start by draining and rinsing the 1 can of canned chickpeas and 1 can of canned black beans thoroughly under cold water. This removes any excess sodium and prevents a metallic taste in your salad. While they drain, dice the 1 whole red bell pepper into ½-inch cubes, removing seeds and membranes for a milder flavor. Peel and chop the 1 whole cucumber into ¼-inch pieces—this size gives you that perfect crunch without overwhelming the dish.

Next, thinly slice the ½ whole red onion and immediately place it in a bowl of cold water for 5 minutes. This simple step mellows the onion's sharpness while keeping it crisp. Drain just before using to prevent a watery salad. Chop the ½ cup fresh parsley and ½ cup fresh dill separately, removing any tough stems. These herbs will bring freshness and depth to every bite.

In a small saucepan, combine the 1 cup French green lentils with 2 cups water and bring to a boil over high heat. Once boiling, reduce to a simmer and cook for exactly 15 minutes—this ensures they're tender but still hold their shape. Drain any remaining water and let them cool completely before adding to the salad. The lentils should be warm but not hot when mixed, so they don't release excess moisture.

While the lentils cook, prepare the optional ½ whole avocado by pitting and slicing it into ¼-inch thick pieces. Keep these separate until the very end to prevent browning from the lemon juice and vinegar in the dressing.

In a small bowl, combine the ½ cup extra-virgin olive oil, ½ cup apple cider vinegar, 1 tablespoon maple syrup, 2 tablespoons fresh lemon juice, ½ teaspoon diamond crystal kosher salt, and ¼ teaspoon ground black pepper. Whisk vigorously until fully emulsified—you should see a smooth, glossy dressing with no visible oil separation. Taste and adjust the balance: need more tang? Add another ½ teaspoon lemon juice. Too sweet? A pinch more salt will brighten the flavors.

This dressing is the heart of your salad, tying together the earthy lentils, creamy beans, and fresh vegetables. The maple syrup adds subtle depth, while the vinegar and lemon juice ensure it stays fresh for hours in the fridge.

In a large mixing bowl, combine the drained beans, cooked lentils, diced bell pepper, cucumber, and drained onion. Gently fold in the chopped parsley and dill, reserving a small handful of each herb for garnish. Pour the dressing over the mixture and toss everything together with your hands or a large spoon. Be gentle—you want to coat the ingredients evenly without mashing the beans or lentils.

If using the optional avocado, add it now and toss just until combined. For the best texture, serve immediately while the avocado remains vibrant. If you need to prepare ahead, keep the avocado separate and add it just before serving.

Cover the salad and refrigerate for at least 30 minutes before serving. This allows the flavors to meld and the dressing to fully absorb into the ingredients. When ready to serve, give it one final toss and transfer to a platter. Sprinkle with the reserved herbs and a final drizzle of dressing if needed. The salad should be vibrant, with a perfect balance of textures—crisp cucumber, tender lentils, and creamy avocado (if using).

This salad keeps well in the fridge for 2-3 days, making it an ideal meal prep option. The flavors actually improve as the ingredients marry, so it's perfect for lunches or picnics. Pair it with warm pita bread or a simple grain salad for a complete meal.

Essential equipment for great bean and lentil salad

Knife Essentials

Your salad prep starts with the right knives—I swear by a sharp 8-inch chef’s knife for dicing veggies and a small paring knife for peeling cucumbers or trimming herbs. For speed, I use the Victorinox Fibrox chef’s knife—it stays sharp longer than most.

A cutting board (I prefer bamboo for its gentle surface) prevents slipping and dulling blades. 🔪

Mixing Tools

A large mixing bowl (at least 8-quart capacity) is non-negotiable for tossing ingredients without spills. I love the OXO Good Grips—it’s sturdy and has a non-slip base.

For the dressing, a small whisk (like the Norpro Whisk) ensures a smooth emulsion. If you hate washing, a collapsible silicone bowl works great for prepping components separately.

Storage Containers

Meal prep is easier with airtight glass containers—I use Leviton glass jars with snap lids to keep everything fresh for 4-5 days. For the dressing, a small mason jar (like Ball brand) lets you shake it up before each use.

If storing avocado separately, wrap it in plastic wrap pressed directly against the flesh to slow browning.

Optional Extras

Want to take it further? A mandoline slicer (like Benriner) makes uniform cucumber and onion slices in seconds. For herbs, a microplane (for lemon zest) or herb scissors speeds up prep.

If you’re prepping for a crowd, a salad spinner (like OXO) removes excess moisture from greens—though this salad’s veggies are sturdy enough to skip it.
