In a bowl combine 3 tbsp pesto, 1 crushed garlic clove, 1/4 tsp crushed red pepper flakes, juice from 1/2 lime and 1/2 tsp kosher salt. Add the 1 1/2 lbs chicken cutlets, coat both sides with the marinade, cover or seal, and refrigerate at least 1 hour or overnight.
In a small bowl whisk 2 tbsp olive oil, 3 tbsp balsamic vinegar, 1 tbsp raw honey and 1/4 tsp kosher salt; set the dressing aside.
Preheat a grill to medium-high. Clean the grates and lightly coat them with olive oil cooking spray to help prevent sticking.
Arrange the 1 lb asparagus (tough ends removed), 2 medium zucchini sliced 1/4-inch thick, and 1 red bell pepper (seeded and sliced into strips) on a large grill tray or two smaller trays (or plan to cook in batches). Spray the vegetables with olive oil cooking spray and sprinkle with kosher salt.
Grill the vegetables, turning constantly, until the edges are browned, about 6 to 8 minutes. Transfer the vegetables to a plate and set aside.
Remove the chicken from the marinade, letting excess drip off. Grill the cutlets 4 to 5 minutes per side, until grill marks appear and the chicken is cooked through.
Transfer the cooked chicken to a platter, top with the grilled vegetables, and pour the balsamic-honey dressing evenly over everything before serving.
