Variation~ Add sauteed, leftover roasted, or steamed veggies to the meat bottom layer: winter squash, onions, broccoli, cauliflower, kale or collards etc. By doing this, you can reduce the amount of meat OR you can just make the pie bigger and more interesting. If you make it bigger, keeping the full amount of meat and adding vegetables, the casserole can be baked in a 9x13" baking dish to feed more people. This will make the top layer thinner; but there will still be plenty.
