1: Chop the broccoli florets into small pieces and put in a microwave-safe bowl with about 2 tablespoons water. Cover with plastic wrap and microwave on high for 2-3 minutes, or alternatively steam on stove-top for 1 minute.
2: Slice each chicken breast horizontally to form a pocket, not cutting all the way through. Season with Italian seasoning, garlic powder, paprika, salt, and pepper.
3: In a large bowl, combine steamed broccoli, bell pepper, garlic, cheddar cheese, cream cheese, Parmesan, and some salt and pepper. Mix well and set aside.
4: Spoon the broccoli mixture into each chicken breast evenly and secure with toothpicks if needed.
5: Preheat the oven to 400F. Heat 1 tablespoon of olive oil in a large cast iron or oven-safe pan over medium-high heat. Add the chicken breasts and cook for 2-3 minutes per side or until golden.
6: Cover the pan with aluminum foil and transfer to the preheated oven. Bake for 15-20 minutes or until the chicken is cooked through.
