First spray your baking dish with a nonstick spray
cut a few pats of butter and place on bottom of baking dish, not close together, but scattered.
Add 1 layer diced yellow potatoes ( I leave the skin on)
Add 1 slice american cheese ( being careful not to let the american cheese touch sides of baking dish, this tends to burn the edge of cheese ) (I use a bean pot to bake mine in, if you use a casserole dish, you will probly use more american cheese, butter per layer)add a few more pats of butter, salt , pepper. next add layer of your choice of meat. sprinkle shredded cheese over the meat.
Then start with pats of butter, then potatoes,salt and pepper , american cheese, then meat, layer shredded cheese
Layer to top and try to end with potatoes,and shredded cheese
Bake in 350 oven until potaoes are cooked thru, Serve hot or warm it up for later!
