You probably have this recipe, so many people I know make this. We all take Campbell mushroom, celery or cream of chicken soup and cover the chicken breast, bake for 1 hour and it's delicious. I serve it with mashed potatoes and the soup makes a great gravy. I have used other off brand soups and find it is more salty than Campbell soup.
Another recipe: Cut 4 chicken breasts into cubes and cook in butter till done. Boil a package of egg noodles and add chicken breast cubes. I use a jar of Alfredo sauce (any flavor) and one jar of milk. Mix together and it's great. You can add extras if you want, but it's very good by itself.
