Mix spices together and pat onto both sides of chicken
Heat olive oil in skillet (that has a lid) on medium heat for 3-4 minutes until hot.
Add chicken to skillet and cook on both sides for 3-4 minutes. Be sure to cover with a lid to keep oil from splattering.
Remove chicken when cooked through to 165 degrees F. Done!

Notes
Chicken is SPICY. Use less cayenne pepper and black pepper to make less spicy. OR, bake it in the oven (slower heat will keep it from getting too spicy).
