Easy Quiche Lorraine

Quiche Lorraine is perhaps the most famous of all quiches. Purists will tell you that only bacon, cream, and eggs are allowed. Though it is common to find other ingredients like Gruyere cheese, caramelized onions, and even chives. The original quiche Lorraine may not include cheese, but I won’t tell anyone if you decide to add one cup of shredded Gruyere to the mix.
