Rinse the green lentils in a fine-mesh strainer under cold water until the water runs clear. I used to skip this and the salad tasted faintly bitter—don't be me. Place them in a dry skillet over medium-high heat and let them toast for two minutes, stirring occasionally, until they smell nutty and warm.

Add the water and bring to a boil, then reduce heat to low and simmer for 25 to 30 minutes until the lentils are tender but still hold their shape. This is the whole game—overcooked lentils become mush and ruin the summer lentil salad crowd texture. Drain any remaining liquid and spread on a clean plate to cool slightly.

While the lentils cook, dice the cucumber, halve the cherry tomatoes, and finely chop the red onion into small pieces so each bite feels balanced. Rough chopping here means some forkfuls are all onion and others miss it entirely. I learned that the hard way at Sandra's family dinner three years ago.

Whisk together the olive oil and lemon juice in a small bowl, then add the salt and black pepper and taste the dressing alone—it should make you pucker slightly, because the lentils will absorb some of that brightness. This is where most crowd lentil salad cookout recipes fail: the dressing tastes weak on its own but perfect once everything comes together.

Combine the cooled lentils with the tomatoes, cucumber, red onion, parsley, and mint in a large bowl, then pour the dressing over and fold gently so nothing breaks. Scatter the toasted pumpkin seeds and grilled chicken across the top, then fold one more time to distribute everything evenly.

Let the salad rest for at least 15 minutes at room temperature so flavors marry before serving—or refrigerate for up to four hours and bring to room temperature thirty minutes before your cookout. The protein disappears fast at cookouts because people taste how the herbs and lentils have absorbed the lemon dressing.
