1 pound of ground beef
1 egg
1/4 cup of dry bread crumbs
1 teaspoon of salt
1 teaspoon of mixed herbs (oregano, basil, marjoram)
1 teaspoon of dry mustard
1/4 teaspoon of ground cumin
1/8 teaspoon of garlic powder
1 1/2 cups of sliced potatoes
1 medium onion, sliced into rings and separated
1 1/4 cups of mushrooms
1 cup of shredded cheddar cheese
1/2 cup of shredded Swiss cheese
2 tablespoon of parsley

Mix the ground beef with the egg, bread crumbs, salt, herbs, mustard, cumin and garlic powder.
Pat evenly into a 9" 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 aluminum foil and bake at 350 degrees for 1 hour or until the potatoes are done.
Remove from the oven and take off the foil and sprinkle the cheese and parsley on top.
Return to the oven just long enough to melt cheese.
