Chicken Breast In Mushroom Sauce Recipe

This recipe was given to me by a close family friend, TT, back when I first headed out on my own.  I used it a lot cause I was always broke and it didn't cost much.  If you want to save money further, get bone-in chicken breasts rather than boneless but you will have to bake for 1 hour.
Preheat oven to 350.  Butter a shallow baking dish.  In a bowl, mix 1 small can Cream of Mushroom Soup with 1 Cup of Sour Cream.  If your budget allows, buy 3-4 Loose Mushrooms, rinse, slice thinly and add them to the mixture.  Add S&P to taste.  If you want, you can add 1 1/2 Cups Frozen Peas at this time.  Spread a small amount of this mixture over the bottom of the baking dish.  Rinse 4 Boneless Chicken  Breasts and add them to the dish.  Top with remaining mushroom mixture.  Sprinkle with Paprika or Parsley or both.  Bake uncovered for 45 minutes or until bubbly and chicken is just done.  It will be very tender.  Let rest for 5 minutes and serve.
