Ham and Scalloped Potatoes

Trying to figure out what to do with that after Christmas Ham? Or that After Thanksgiving Ham? Or that after Easter Ham? Or that after My-Husband-Just-Loves-Ham Ham?  This is a great recipe for thinking outside of the ham sandwich box!

8-10 slices of ham
8-10 medium potatoes, peeled and sliced thinly
1/2 of one large onion, sliced
1 C. grated cheddar cheese
2 cans cream of mushroom soup
Salt and pepper to taste

Toss the sliced potatoes in 1/2 teaspoon cream of tartar and 1 cup of water.  Drain.  Put half of ham, potatoes, and onions in a crockpot (I like to spray the crockpot with cooking spray first).  Sprinkle with salt and pepper, then cover this layer with one can of the cream soup (not diluted) then half the cheese.  Repeat with the remaining half of your ingredients.  You can also sprinkle this with paprika if you want.  Cover and cook on low for 8-10 hours or high for 4 hours or until the potatoes are cooked through.
