  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 1 large red bell pepper, 2 sliced zucchinis, 1 medium red onion wedges, and 3 minced garlic cloves with 1 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Spread vegetables on a baking sheet and roast for 20-25 minutes until tender and lightly caramelized.
  2. Step 2: Meanwhile, brush 4 boneless skinless chicken breasts with 2 tbsp olive oil, then rub evenly with 2 tbsp Cajun seasoning, 1/2 tsp salt, and 1/4 tsp black pepper. Let rest for 10 minutes.
  3. Step 3: Heat a grill or grill pan over medium-high heat. Grill chicken breasts for 6-7 minutes per side until internal temperature reaches 165°F and chicken is charred slightly. Remove and rest 5 minutes.
  4. Step 4: Serve the grilled Cajun chicken with the roasted vegetables and lemon wedges for squeezing over top.
