This is a very easy and inexpensive Santa Fe Chicken skillet that is packed with protein from chicken and beans as well as fiber from onions and peppers.
In a large skillet over medium-high heat, heat olive oil. Add chicken and cook until no longer pink. How many minutes per side depends on the thickness of the chicken breast, generally at least 5 minutes per side. Transfer to a plate.
Vegetable Mixture:
Add garlic, onion, and red pepper to skillet and cook until tender, about 10 minutes. Stir in black beans until warmed through, then transfer mixture to a bowl
Reduce heat to low and return chicken to skillet. Top with cheddar, cover with lid and let heat until cheese is melted.
Spoon the mixture all over chicken when ready to serve. Garnish with parsley.
