Derived from a Pillsbury Bake-Off winner in the 70s, this recipe is just a summer squash-onion quiche, Italianized. The Queen included it in the church cookbook she edited in the 80s, and we’ve made it at home ever since. The best way I know of to use all that zucchini that overwhelms the neighbors’ gardens every summer.
You may wonder why it’s called “zucchini crescent” pie. The original recipe calls for using Pillsbury Crescent Rolls arranged in a pie tin to make a pretend pie crust. That works OK, if you must.
