Best Egg Casserole I have ever had.

Seriously, if you are ever asked to bring an egg casserole to something...cause that happens ALL THE TIME...uh....well anyway, IF you ever do, you must bring this. Your praises will be sung.

Peggy's Quiche

32 oz. cubed frozen potatoes (try the ones with bell pepper and onion for extra flavor)
1 Cup melted butter (you can reduce to 1/2- 3/4 if that just made you faint)
2 cups diced ham, you know, cubed.
2 cups grated chedder cheese (I recommend sharp or medium)
2 cups grated monterey jack cheese
1 cup evaporated milk
6 eggs
1/2 tsp seasoning salt
black pepper

Spray 9x13 baking pan with cooking spray. Press potatoes in pan to form crust. Pour melted butter over potatoes. I would salt and pepper the potatoes too. Bake at 425 for 20 minutes. Remove pan from oven and make alternate layers of cheese and ham. Reduce heat to 350. Beat eggs, milk, and seasoning salt. Pour egg mixture over cheese and ham. Bake for 30-45 minutes until knife comes out clean.
