Bake 5-7 minutes more or until pastry is nearly done. Remove from oven. Reduce oven heat to 325degrees. Stir together eggs, milk, green onions, salt, pepper, and nutmeg in a bowl. Stir in meat. Toss the cheese and the flour together. Add to egg mixture. Mix well. Pour egg mixture into hot pastry shell. To prevent overbrowning, cover edge of crust with foil.
