Here is the Breakfast Casserole recipe that I made for a Sunday lunch. It is adapted from a recipe in our ward cookbook.
1 large bag of hash browns (although I bought a large bag and didn't use the whole thing)
1/2 onion chopped (You can add onions or buy hash browns with onions)
1-2 cups of grated cheese
Meat of choice: 8 oz of cooked breakfast sausage crumbled or 1 cup of cooked chopped up ham or
1 pound of bacon cooked and crumbled (I used ham)
1/2 tsp salt
1/2 garlic salt
Pepper to taste
Pour frozen hash brown in greased 9X13 pan. place meat in a layer on top of hash browns. In a large bowl beat eggs with a whisk and add 1/2 tsp of salt, 1/2 tsp of garlic salt, and pepper. Pour egg mixture on to hash browns and meat. Top with cheese. You can now refrigerate overnight if you want to eat it for breakfast or go ahead and bake it now. Bake at 425 for 20 minutes, turn oven down to 375 and bake 20 minutes longer.
