This recipe is called the 'Poor Man Husband Casserole' but you'll feel nothing but rich after eating it

Transfer the ground beef mixture to a greased 9x13-inch baking dish, spreading it out evenly.
Spoon the mashed potatoes over the beef mixture, spreading them to cover the entire surface.
Sprinkle the shredded cheddar cheese evenly over the mashed potatoes.
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.
Once baked, remove the casserole from the oven and let it cool for a few minutes before serving.
