Follow these simple steps to create your own Hawaiian Chicken Sheet Pan:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare the Pan: Line a large sheet pan with parchment paper or tin foil for easier cleanup.
3. Mix the Sauce: In a bowl, combine the soy sauce and diced pineapple. Stir until well mixed.
4. Arrange Chicken: Place the chicken pieces on the prepared sheet pan and pour half of the pineapple-soy sauce combination evenly over them.
5. Add Vegetables: Scatter the sliced bell peppers around the chicken on the pan.
6. Pour Remaining Sauce: Drizzle the remaining sauce over the chicken and vegetables for extra flavor.
7. Bake: Place the sheet pan in the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
8. Broil (Optional): For an additional caramelized effect, you can turn on the broiler for an extra 2-3 minutes at the end of cooking.
9. Garnish: Remove the pan from the oven and let it cool for a couple of minutes. Garnish with chopped green onions if desired.

The steps above will ensure that your Hawaiian Chicken Sheet Pan turns out succulent and bursting with flavors every time.
