Rub Mrs. Dash seasoning on both sides of the chicken.
Heat oil in a large nonstick skillet. Cook chicken in oil over medium heat for 4-6 minutes each side, or until the juices run clear. Transfer chicken to a plate.
Rinse and drain the beans.
Add beans, corn, and salsa to the pan and cook about 3-4 minutes.
Sprinkle one tablespoon cheese on the chicken and allow it to melt. If it does not melt you can microwave the chicken with the cheese on it for 15-30 seconds.
Serve 1/2 cup of the bean mixture with 4 ounces chicken.
