Step 1: Preheat the Oven - Start by preheating your oven to 400°F (200°C) to ensure the chicken cooks evenly and the veggies get nice caramelization.
Step 2: Prepare the Marinade - In a mixing bowl, whisk together the balsamic vinegar, honey, Dijon mustard, and minced garlic.
Step 3: Marinate the Chicken - Add the cut chicken pieces to the marinade, ensuring each piece is well-coated. Let it marinate for at least 15 minutes.
Step 4: Arrange the Veggies - On your sheet pan, arrange the chunks of bell peppers and onion. Drizzle with olive oil and sprinkle with salt, pepper, and chopped fresh basil.
Step 5: Add the Chicken - Once the chicken is marinated, add it to the sheet pan with the veggies and pour any remaining marinade over the top.
Step 6: Roast in the Oven - Place the sheet pan in the preheated oven and roast for about 25-30 minutes, or until the chicken is cooked through and the veggies are tender.
Step 7: Serve and Enjoy - Let the dish rest for a few minutes before serving warm, garnished with additional fresh basil if desired.
