Bring water to a boil in a large pot. Add rinsed lentils and thyme sprigs. Reduce heat to medium-low and simmer for 20 minutes until lentils are just tender but still hold their shape. Drain and set aside.
Tip: Don't overcook the lentils or they'll fall apart on the grill.

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add sliced onions and cook, stirring occasionally, for 8-10 minutes until they begin to soften and turn golden.
Tip: Don't rush this step—patience creates deep caramelization.

Reduce heat to medium-low and continue cooking onions for another 8-10 minutes, stirring frequently, until deeply caramelized and sweet. Add balsamic vinegar and minced garlic in the last minute of cooking.
Tip: If onions stick, add a splash of water to deglaze the pan.

Preheat grill to medium-high heat (around 400°F). In a large bowl, combine cooked lentils with caramelized onion mixture, remaining 2 tablespoons of olive oil, vegetable broth, salt, and pepper. Toss gently to combine.
Tip: The vegetable broth helps keep the lentils moist during grilling.

Transfer lentil mixture to a grill basket or perforated grill pan. Place on grill and cook for 8-10 minutes, stirring occasionally, until the lentils develop charred spots and edges are crispy.
