Preheat oven to 400 degrees F.
Place potatoes across the bottom of (uncooked) pie shell.
Top with sausage, ham, and cheese.
Place pie pan on a cookie sheet.
In a medium bowl, whisk together eggs, milk, and desired seasonings.
Pour egg mixture over the meat, cheese and potatoes.
Bake for 35 to 40 minutes or until eggs are set. (If crust begins to get too dark, place aluminum foil around the edges to prevent burning.)
