Mom would always try to sneak in vegetables, much to our dismay. It is pretty hard to hide a can of green beans, even if it is surrounded by gravy. But, you can always try that too.
1 pound ground beef, browned and drained
2 packages brown gravy mix, mixed with water
6 cups mashed potatoes
2 cups grated cheese
Mix gravy and ground beef
Pour ground beef in a 9x13 pan. Layer mashed potatoes on top, then cheese.
Bake at 350 degrees for about 20 minutes, or until cheese is bubbly.
