Slice the potatos {in rounds}with the skins on if you like.
Layer them with chopped onion and the chedder soup that has been mixed with about a cup of milk,
a layer of the chopped onions and a layer of cheese.
Salt and pepper each layer, ending with the cheese covering the top.

Bake at about 350 for about an hour, or until browned and bubbly.

Remember the layering is: potatos-
salt and pepper-
chopped onions-
soup mixture
-shredded cheese,
ending with the cheese covering the top. I use a glass baking dish.
