This is a Master recipe perfected over the years. You choose the ingredients you like to make it your way. You can leave out the meat and substitute veggies (grated or chopped) like carrot, zucchini, tomato, broccoli, etc. for a vegetarian meal. It goes great with a salad. Also makes a tasty party nibble or appetizer cut in smaller portions. This quiche can be served hot or cold and can be frozen after baking.
I often make more than one and wrap up individual portions for reheating (microwave or oven) later.
