1 lb. ground beef
1 egg
1/4 c. bread crumbs
1/2 tsp. salt
1 tsp. mixed Italian dried herbs (oregano, basil, marjoram)
1 tsp. dry mustard
1/4 tsp. ground cumin seeds
1/8 tsp. garlic powder (optional)
1 1/2 c. sliced, peeled potatoes
1 med. onion, sliced and separated into rings
1 1/4 c. sliced mushrooms
1 c. shredded Cheddar cheese
1/2 c. shredded Swiss cheese
2 tbsp. chopped fresh parsley or dried parsley flakes

Mix beef with egg, crumbs, salt, herbs, mustard, cumin, and garlic powder. Pat evenly into a 9 inch pie pan to make a crust. Fill crust with a layer of potatoes, onion, and mushrooms, reserving some mushrooms to ring the pie. Cover with foil. Bake at 350 degrees for one hour or until potatoes are done. Remove from oven. Remove foil. Top with cheeses and sprinkle with parsley. Return to oven just long enough to melt cheese. You can assemble the hamburger pie ahead, cover and refrigerate for baking later.
