Preheat oven to 350 degrees.Grease a large casserole pan.Layer the shredded cheese and cubed ham along the bottom of the pan.(Tip: You can also add chopped bell peppers, artichoke hearts, mushrooms or spinach to the bottom layer.)Combine the remaining ingredients and pour over the ham and cheese (and anything else you've put on the bottom).Bake at 350 degrees for 45-55 minutes.(I like to sprinkle real bacon bits and cheddar cheese over the top for the last 10 minutes.)You may also want to serve it with salsa and sour cream.You can make this the night ahead -- either baking in advance or the morning of!
