Wash the mini peppers and cut them in half lengthwise. Remove the seeds and membranes.
Heat oil in a large skillet over medium heat. Add the chopped onion and minced garlic to the skillet and sauté until the onion is soft and translucent.
Add the shredded rotisserie chicken and black beans to the skillet. Stir in the taco seasoning and cook for 2-3 minutes until everything is well combined and heated through. If the mixture looks dry, you can add a tablespoon of water.
Place the halved mini peppers on a baking sheet, cut side up. Spoon the chicken and bean mixture into each pepper half, pressing gently to fill them. Sprinkle shredded cheese evenly over the stuffed peppers.
Bake in the preheated oven for 10-15 minutes or until the cheese is melted and bubbly. Remove from the oven and let cool slightly. Garnish with chopped cilantro if desired.
Serve with sour cream, salsa, and avocado on the side.
Notes
Ensure the oven is preheated before baking. This helps the peppers cook evenly and develop a nice, roasted flavor.
Do not skip sauteeing the onion and garlic before mixing them with the shredded chicken and other ingredients. This step enhances their flavors and ensures they blend seamlessly into the filling.
Resist the urge to overfill the peppers, as this can cause them to split. Fill them to about 3/4 capacity and gently press the filling down.
