I found this recipe several years ago and it has become a family favorite....it was also a favorite when I did my cooking group as well.
2 cups crushed Ritz Crackers
3 T grated parmesan cheese
2 t garlic salt
8 boneless skinless chicken breasts(we like dark meat so I use boneless skinless thighs as well)
1 cup plain yogurt
1/4 cup melted butter
Combine crackers crumbs, Parmesan cheese and garlic salt(I crush them all together in a ziploc bag and then put it in a bowl). Dip each piece of chicken in yogurt to coat and then in the crumb mixture.
Arrange in greased 9x13 pan. Drizzle with melted butter. Bake at 350 degrees for about 45 minutes.
Top with the following sauce:
2 cans cream of chicken soup
1 cup sour cream
Combine soup and sour cream together in a pan over low heat. Serve over chicken.
