1 lb burger (or other ground meat to your preference)
1 c peas or mixed vegets, cooked
2 c mashed potato (Actually, I’d suggest just making a lot and using however much you need.  Can always make mashed potato pancakes or something with any excess.)
1 egg
1/4 c parsley
1 diced onion
1 diced clove of garlic (or more.  or lots more.)
1 1/2 tsp Old Bay seasoning (I actually don’t follow this part anymore.  Tailor it now to what I think will taste right or what I think the people I’m feeding need.)
Hunter’s Gravy (or any decent brown gravy.  Can make pan gravy if you have the time.)

Saute onion and garlic and burger.  Mix with vegets, seasoning, sauce.  Add butter (as needed), salt (to taste), parsley, and egg to potatos.  Grease a casserole, fill with a third with potato mix, cover with burger, leaving enough space for a potato mix “lid.”  Brush with melted butter.  Bake at 400 for 30-40 minutes, covered for the first bit, uncover for last 10 minutes or so to let the top brown.  (Made a really random tasty sauce for it once that consisted of something along these lines, as weird as it may seem:  W-sauce, dill, curry, salt, pepper, basil, thyme, and a bay leaf.)
