Mix beef with egg, bread 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 for 1 hour or until potatoes are done.
Remove from oven.
Top with cheese and sprinkle with parsley.
Return to oven just long enough to melt cheese.
