This is the absolute easiest breakfast casserole on the planet.  I have already professed my deep love of canned biscuits, so this was a no-brainer when I saw the recipe.  It has the Sunday School stamp of approval as well.  We all take turns bringing breakfast, so that we only cook once every three months.  Pretty nice.  I fed 30 people for less than $10.  Each recipe is for an 11 x 7 pan.  Preheat the oven to 350 degrees.  Get a can of the Pillsbury Grands Flaky biscuits and quarter each biscuit.  In a bowl, mix 1 egg and 2 tablespoons of milk.  Toss the biscuits in the mixture.  Then mix in one package of cooked crumbled breakfast sausage and 1 cup of cheese.  Put it in your greased pan and bake for 25 minutes or until it is as brown as you like.  I can't express how great it is.  You can also use bacon.  Adding green onions can bring a little more flavor to the bacon version, if you can tolerate such a thing for breakfast.  Give this a try and let me know what you think.
