Chicken and Mushrooms

This is very quick and easy and tastes good.

1 T. olive oil
1/4 c. chopped onions
1 pound chicken breast
1 can cream of mushroom soup (use Campbell's Healthy Request; less sodium and fat)
1 to 2 cups sliced mushrooms
1/2 cup water or wine if desired

Heat oil in skillet. Either pound out breasts or cut in half horizontally so they are not too thick. When oil is heated, saute onions. Add breasts and brown on both sides. Add salt and pepper if desired. Add mushrooms and saute lightly; then add mushroom and water or wine. Bring to light boil, then lower and cover for 15 to 20  minutes to allow chicken to cook through. Serve over rice.
