Crockpot Scalloped Potatoes and Ham

1/2 - 1 lbs of cubed, cooked ham
6-8 raw potatoes, sliced
1 C onion, chopped (divided)
1 C grated cheddar cheese
1 C grated mozzarella cheese
1 T olive oil (or butter)
1 can (4oz) of mushrooms, drained (may use fresh as well)
1/2 C chicken broth
1/2 C milk
1 T cornstarch

In a saucepan, saute 1/2 C onions with mushrooms in 1 T oil or butter until onions are translucent (about 5 minutes). Add chicken broth and heat to boiling. Mix 1/2 c milk with cornstarch until well mixed, and add to the boiling mixture, stirring frequently until thick (about 1 minute). Season with salt and pepper, if desired. Set aside. **Alternatively, you can use cream of mushroom soup from a can.

Put half of the ham, potatoes and onions in a crock pot. Sprinkle with salt, pepper and half of both cheeses.Repeat layers. Spread home-made mushroom soup (in saucepan) over the top, completely covering the potatoes.

Cover and cook on low for 8 hours or until potatoes are tender.
