Creating Hawaiian Chicken Sheet Pan is a straightforward process, especially when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare Chicken: Pat the chicken breasts dry with paper towels. This ensures they get a nice sear.
3. Season Chicken: In a bowl, mix olive oil, garlic powder, onion powder, paprika, salt, and black pepper. Rub this mixture all over the chicken breasts for even flavor.
4. Arrange on Pan: On a large sheet pan, spread out the seasoned chicken, pineapple chunks, sliced bell peppers, and onion wedges in an even layer.
5. Bake: Place the sheet pan in the preheated oven and bake for about 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
6. Garnish: Once cooked, remove the sheet pan from the oven. Let it rest for a few minutes before garnishing with sliced green onions and fresh cilantro.
7. Serve: Slice the chicken and serve the dish hot, ensuring everyone gets a portion of chicken, veggies, and pineapple.
