Preheat the Oven: Set the oven to a temperature of 400 degrees Fahrenheit to ensure it is adequately heated before cooking.
Prepare the Baking Dish: Utilize a non-stick spray to coat a 9x13 inch baking pan thoroughly to prevent sticking during the baking process.
Season the Chicken: Position the chicken breasts evenly within the pan. Sprinkle each piece uniformly with salt and pepper to enhance flavor.
Add Pineapple and Barbecue Sauce: Distribute the pineapple chunks over the seasoned chicken breasts. Follow by drizzling the honey barbecue sauce over the top, ensuring each breast is adequately covered.
Bake: Place the pan in the preheated oven and bake for 30 to 40 minutes. The chicken is properly cooked when it reaches an internal temperature of 165 degrees Fahrenheit, as measured by a food thermometer, ensuring both safety and tenderness.
