I just made this for supper. It's really, really easy, quick to put together, and inexpensive. It does take a while to cook, though.

Ham and Potatoes Au Gratin
Serves 2-4
Oven at 350 or crockpot on low.

1/3 c.Cream Soup Mix
1 1/4 c. water
1 1/2 c. shredded cheddar cheese
about 1/2 lb. ham, cooked and diced
4 medium potatoes, peeled and sliced thinly
crumbled cheese crackers and extra cheese for top, optional for oven baking

Whisk the cream soup mix into the water and microwave in 30 second intervals, whisking between, until it reaches desired consistency. Meanwhile, start peeling and slicing the potatoes. Stir the cheese into the soup mixture. 1 1/2 c. of cheese is just a guess on my part, as I don't measure it. Place the diced ham and sliced potatoes in crockpot or casserole dish and pour sauce over. Stir to coat. Add crackers and cheese to the top if you're into the crunchy top thing. Cook in crockpot on Low for 8 hours, or in the oven at 350 for about an hour and fifteen minutes.

I'll admit to liking it better from the oven, but if I'm going to be out all day or if I'm making it in warmer weather, the crockpot is good enough. Leftover type ham seems to give the dish a good deal more flavor than, say, deli ham or the stuff you'd buy already diced.

And obviously you can leave out the ham and this makes a good side dish too.
