Making Sheet Pan Hawaiian Chicken with Pineapple and Peppers is a simple process. Follow these easy steps for a delicious meal:

1. Preheat Your Oven: Start by preheating your oven to 400°F (200°C).

2. Prepare Chicken: Cut the chicken breasts into bite-sized pieces.

3. Mix Marinade: In a bowl, whisk together the soy sauce, honey, olive oil, garlic powder, ginger powder, black pepper, and red pepper flakes if using.

4. Combine Ingredients: In a large mixing bowl, add the chicken pieces along with the pineapple chunks, bell peppers, and onion. Pour the marinade over all the ingredients, then toss until everything is well coated.

5. Arrange on Sheet Pan: Spread the chicken mixture out evenly on a large baking sheet in a single layer.

6. Bake: Place the sheet pan in the preheated oven and bake for 30-35 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).

7. Garnish and Serve: Once cooked, remove from the oven and let it sit for a few minutes. Garnish with fresh cilantro if desired.
