Spray the bottom of a baking dish or pan with oil and place the chicken on the bottom. Pour about a half cup or more over the chicken pieces. Just be sure the chicken is well-coated. Layer with the sliced onions and place the crumbled Feta cheese over the top. Cover with foil and bake for 45 minutes at 325 degrees. Remove foil and continue baking for 15 minutes or until the Feta cheese is slightly browned.
I served this dish with baked potatoes and a lettuce salad. Delicious! Thanks, Dean and Brady!
