Brown chicken breasts in a little olive oil and butter just until they are partly done. Take them out and add 2 cans of any variety of chicken soup and a 16 oz. container of sour cream. Stir on low until it's mixed together well and add the chicken back into the gravy. Spoon the gravy on top of the chicken and continue to cook on low to medium until the chicken is done, turning several times so it can absorbe the gravy's flavors. Serve with rice and vegetable of your choice. The gravy is great over the rice as well as the chicken.
