Step 1: Preheat your oven to 375°F (190°C). Prepare the bell peppers by halving them lengthwise and removing the seeds and membranes.
Step 2: Place the halved bell peppers cut side up in a baking dish. Drizzle with olive oil to help them soften and prevent sticking.
Step 3: Bake the bell peppers for about 10 minutes to soften them slightly before adding the filling. This step ensures that the peppers cook evenly and become tender.
Step 4: While the peppers are baking, prepare the filling. In a large bowl, combine the cooked chicken, cooked rice, drained pineapple tidbits, teriyaki sauce, garlic powder, onion powder, and black pepper.
Step 5: Mix the ingredients thoroughly until everything is evenly coated with the teriyaki sauce and spices. This ensures a consistent and flavorful filling.
Step 6: Remove the partially baked bell peppers from the oven. Carefully stuff each half with the prepared chicken and rice mixture, pressing down gently to fill them well.
Step 7: Sprinkle the tops of the stuffed peppers generously with shredded mozzarella cheese or your preferred cheese blend.
Step 8: Return the stuffed peppers to the oven and bake for another 15–20 minutes or until the cheese is melted and bubbly and the peppers are tender.
Step 9: Remove the baked stuffed peppers from the oven and let them cool slightly before serving.
Step 10: Garnish with sliced green onions and sesame seeds, if desired, for added flavor and visual appeal. Serve warm and enjoy!
