Squash Casserole

3-4 medium yellow squash(thinly sliced)
1 onion (sweet or Vidalia) (thinly sliced)
1/2 stick butter
1 cup Extra Sharp Cheddar Cheese (grated)
1 egg
1/4 cup - 1/2 cup Milk
1/2 sleeve Saltine crackers (crushed)
salt and pepper

In a casserole layer sliced squash, sliced onion, salt, pepper, butter pads, cheese, then second layer. Top with crushed crackers, butter. Beat together egg and milk. pour over casserole. (May need a little more milk, depending on how deep the casserole. Press down on the casserole.) Bake at 350 for 45-min. to an hour or until top is browned. I've also used zucchini with the yellow squash and patty pan squash. What's fun about cooking is you can adjust recipes to your liking!
