Preheat your oven to 400°F (200°C) and lightly spray a baking dish with oil.
Arrange the thinner chicken breasts in the prepared dish. Season generously with salt and black pepper.
Spoon the low-sugar BBQ sauce over each chicken breast, ensuring they are well coated.
Evenly sprinkle the 1 cup of diced pineapple over the sauced chicken.
Next, scatter the diced cooked bacon and thinly sliced red onion over the pineapple layer.
Finally, top with the shredded Mozzarella cheese. Bake for 25-30 minutes, or until the chicken is thoroughly cooked through.
For a perfectly golden and crispy cheese topping, broil for an additional 3-4 minutes. Before serving, garnish with the reserved diced pineapple and fresh green onions.
