Heat olive oil in a large skillet over medium heat. Add bell peppers and onions, cooking for 5-7 minutes until softened.

Push veggies to the side, add marinated chicken, and cook for 5-7 minutes until browned and cooked through.

Sprinkle cheese over chicken mixture, cover skillet, and let cook for 2-3 minutes on low heat to melt cheese.
