I usually make this in the colder months, around the holidays. Not only is it a good way to use leftovers, but baking warms up the house and the smell is great. The family loves it. I have used chicken, turkey, and even ham...yes, I tend to be adventurous. Pot roast works well also. Of course, there are some ingredients that some of you may decide to leave out, by all means, make it the way that suits your taste! I will admit that I have used variations on this recipe, but the main ingredients are the same...meat, vegetables, crust. Enjoy!
