Gather Your Ingredients

  • Lentils: Choose green black brown or French types for the best texture They are the base for protein and fiber Select canned for convenience or cook dried ones for maximum flavor and fewer additives
  • Cherry tomatoes: Quartered for sweetness and juiciness Look for firm ripe tomatoes or substitute plum tomatoes
  • Cucumber: Diced for crunch and freshness Go for a medium cucumber that feels heavy for its size
  • Red onion: Thinly sliced or diced for sharp kick and color Choose onions with firm skins and no bruises
  • Olives: Kalamata or Taggiasche add brine and depth Look for ones stored in brine not oil for pure flavor
  • Parsley: Freshly chopped for herbal brightness or swap in dried oregano for a different vibe
  • Feta cheese: Adds creamy salty notes Non-dairy feta works just as well Buy a block and crumble it yourself for better taste
  • Extra virgin olive oil: Cold pressed for a rich peppery dressing Splurge for the best flavor possible
  • Lemon juice: Freshly squeezed for acidity and zing Your salad will taste fresher than with bottled
  • Dijon mustard: For tang and a silky texture You can also use American mustard if you prefer
  • Garlic: Grated fresh garlic blends smoothly and brings a kick Choose firm cloves for best results
  • Cumin: Optional for warmth and subtle smokiness Use freshly ground for a boost
  • Salt: Essential to highlight flavors Use a flaky or kosher salt for more control
  • Black pepper: Freshly cracked to finish for a mild heat

Feta cheese is my favorite ingredient here It adds a creamy salty kick that brings all the components into harmony Once my daughter helped crumble the feta and now she asks to do it every time The salad feels even more special when we make it together

Flavor Boosters

Store lentil salad in a sealed container in the coldest part of your fridge It keeps beautifully for up to four days making it great for lunches or a quick grab and go dinner The flavors blend more as it sits so leftovers often taste better the next day If you plan to add delicate greens or avocado do so just before serving to retain their freshness

Serving Suggestions

Spoon the lentil salad over baby arugula or spinach for a leafy lunch It pairs well with grilled proteins like chicken or fish for a full meal Layer it into pita pockets with extra veggies and drizzle of yogurt for a quick picnic item The bright flavors also complement spicy main dishes or creamy soups beautifully

Creative Twists

Feel free to swap lentils for drained canned chickpeas for a change of pace Sun dried tomatoes sliced fennel or marinated artichokes can replace any veggies you lack No feta Use crumbled tofu with a dash of salt and lemon or even shredded hard cheese for a different finish Lemon juice can be replaced with apple cider or red wine vinegar for a tangy twist
