My grandmother and Great Aunt Mary used to make zucchini pie every summer. Zucchini pie is not quite a quiche but not really a frittata either. The recipe that they used called for Bisquick baking mix and ½ cup of oil.
It smelled great while it was baking and was also a great way to use up garden zucchini. It packs well for picnics, potlucks, or brown bag lunches. Served with crusty bread and a salad it can be a light supper.
This recipe is mash up of the zucchini pie I remember from growing up but lightened up with inspiration from the Crust-less Summer Zucchini Pie recipe from the Skinnyaste blog. I prefer the zucchini sliced rather than shredded and use only Parmesan rather than a combination of mozzarella and Parmesan. Although, I am sure the combination of both cheeses would be delicious too.
