Ham and Cheese Quiche

I was looking for something different to make that was either low-carb or high-protein. I found this very easy recipe online and it has become a quick favorite. Sometimes I add bacon, sometimes spinach and sometimes just leftovers in the refrigerator. The entire family loves it.
