Preparation:
Preheat oven to 375 degrees. Before baking, place foil around pastry edges to prevent burning crust. Blend beaten egg, half and half, salt, pepper, and cheeses in mixing bowl. Saute green chiles, green onions and mushrooms in margarine. Add to egg mixture, pour into pastry shells and bake at 375 for 45 minutes or until set. Ten minutes before the quiche is ready to be taken out of the oven, remove foil from pastry edges |
