Quiche is a baked flan that is made with eggs with savory fillings such as cheese, meat, seafood, or vegetables. It is a popular brunch recipe that also works well for breakfast or lunch. Recently, I've been watching my carb intake, so I decided to make a crustless version of this recipe. The recipe is also quite versatile in the sense that you can substitute any vegetable or filling you prefer. Simply follow my procedure below. Enjoy!
