What a great idea.
I made quiche during the Christmas holidays when my family was here. It was a real hit. I made one in a quiche dish, and a lot more in little mini muffin tins. Anyway after I had made it, and tasted it, I wondered why in the heck I have not been making this more often.... I haven't made it for years in fact. When you realize how easy it is to make, it's really amazing that more people don't make it. None of my family makes it and none of my friends do either.... it's a great and easy treat.
Now pizza quiche, - wow.. this sounds really good. I'm glad you posted that, as I had never thought of that
