If there's one recipe that has single-handedly carried me through the busiest seasons of my life, it's this Meal Prep Vegan Lentil Salad. I first threw it together on a frantic Sunday night five years ago when my calendar was already groaning under the weight of back-to-back meetings, evening classes, and a cross-country flight squeezed into the same week. I needed something that would stay bright and flavorful for days, deliver complete plant protein, and—honestly—look cheerful enough to make me want to open the container at 1 p.m. when my inbox was overflowing. One taste of the citrusy, herb-flecked vinaigrette against earthy lentils and I was hooked. Since then, this rainbow-colored powerhouse has traveled with me to conferences, beach picnics, and more office lunchrooms than I can count. Whether you're vegan, vegetarian, or simply trying to squeeze more plants onto your plate, this salad is your weekday superhero.

Ingredients You'll Need
Great lentil salad starts with great lentils. Look for French green lentils (a.k.a. lentilles du Puy) if you can—their skin is thinner, so they stay intact and creamy instead of turning mushy. In a pinch, everyday brown lentils work; just shave two minutes off the simmer time. Quinoa adds fluffy texture and complete amino acids; rinse it under cool water for 30 seconds to remove natural saponins that can taste bitter.
Choose heirloom cherry tomatoes for their sweet-tart balance. If tomatoes are out of season, substitute diced roasted red peppers (jarred in water) for a smoky twist. Persian cucumbers stay crisp longer than English cukes thanks to their tight seed cavity. For the red bell pepper, pick one with glossy, taut skin; it should feel heavy for its size, indicating juiciness.
When shopping for parsley and dill, look for bunches that are perky, not wilted. Store them like flowers in a jar with an inch of water, covered loosely with the produce bag—they’ll last a week. Kalamata olives add briny depth; buy them pitted to save time. For the vinaigrette, use a neutral extra-virgin olive oil (fruity but not peppery) so the lemon shines.
Finally, raw sunflower seeds toast in seconds in a dry skillet and cost pennies compared to pine nuts. If you have a nut allergy, pumpkin seeds are an equally crunchy swap.
How to Make Meal Prep Vegan Lentil Salad with Lemon Vinaigrette
Cook the lentils
Rinse 1 cup dry lentils under cold water. In a medium saucepan, combine lentils with 3 cups water, ½ tsp salt, and a bay leaf if you have one. Bring to a boil, reduce heat to low, cover, and simmer 18–20 min until just tender but not mushy. Drain any excess water, discard bay leaf, and spread lentils on a rimmed sheet pan to cool quickly—this stops carry-over cooking and keeps them intact.
Simmer the quinoa
While lentils cook, rinse ½ cup quinoa. In a small saucepan, combine quinoa with 1 cup water and a pinch of salt. Bring to a boil, cover, reduce heat to low, and cook 15 min. Remove from heat, keep covered 5 min, then fluff with a fork. Spread on a second plate to cool completely—hot grains will wilt herbs later.
Whisk the lemon vinaigrette
In a small jar, combine ¼ cup fresh lemon juice, 2 tsp Dijon mustard, 1 tsp maple syrup, ½ tsp salt, and ¼ tsp black pepper. Let sit 5 min so salt dissolves, then add ½ cup olive oil. Seal jar and shake vigorously until creamy and emulsified. Taste—if your lemon is mild, add an extra squeeze; the dressing should make your lips pucker slightly.
Toast the seeds
Place a small skillet over medium heat. Add ⅓ cup raw sunflower seeds and toast 2–3 min, shaking pan often, until golden and fragrant. Transfer immediately to a plate to stop browning—they’ll taste bitter if left in the hot pan.
Dice the vegetables
Halve 2 cups cherry tomatoes, dice 1 cucumber into ÂĽ-inch cubes, finely chop 1 red bell pepper, and thinly slice 3 green onions. Keep everything roughly the same size so each forkful is balanced.
Chop the herbs
Finely chop 1 cup flat-leaf parsley leaves (no stems) and ¼ cup dill fronds. Pat dry with paper towels—excess moisture will waterlog the salad.
Combine everything
In your largest bowl, gently fold together cooled lentils, quinoa, vegetables, olives, and herbs. Pour over about ¾ of the vinaigrette and toss until everything glistens. Taste and add more dressing if needed—remember flavors mute slightly when chilled.
Pack for meal prep
Divide salad among five 24-oz glass jars or meal-prep containers. Top each with 2 Tbsp toasted sunflower seeds just before sealing—this keeps them crunchy. Refrigerate up to 5 days. Serve cold or at room temp; if you like a citrusy lift, squeeze an extra lemon wedge over top on serving day.
Expert Tips
Salt the cooking water
Salting lentil water seasons them from the inside out. Aim for ½ tsp per cup of dry lentils—more and skins toughen, less and they taste flat.
Cool before mixing
Hot grains will steam herbs and turn them army-green. Spread on a plate and refrigerate 10 min for a quick chill.
Double the dressing
Make a second batch and keep it in the fridge—grain bowls and roasted veggies will thank you all week.
Jar layering hack
Pour 2 Tbsp dressing at the bottom, layer lentils/quinoa next, finish with tomatoes and cucumbers up top—no soggy vegetables.
Revive with acid
By day 4, a quick squeeze of lemon or splash of vinegar will brighten flavors instantly.
Freeze extra lentils
Cook a double batch and freeze in 1-cup portions. Thaw overnight for instant salads, soups, or tacos.

Storage Tips
Stored in airtight glass containers, this salad keeps beautifully for up to 5 days. The vinaigrette acts as a natural preservative, keeping vegetables crisp. If you add avocado, dice it fresh on serving day to prevent browning. Sunflower seeds (or any nuts) stay crunchiest when sprinkled on just before eating—stash a small jar of them at your desk. The salad is safe to transport at room temperature for up to 4 hours, making it ideal for plane rides or road trips. If you need longer storage, freeze portions of just the lentil-quinoa mixture (minus veggies) for up to 3 months; thaw overnight, refresh with vinaigrette, and toss with fresh produce.
