It’s a mashup that keeps to the same cuisine: pizza, and a flattish beaten-egg dish topped with anything you like (frittata). Who didn’t try to forge pizza with a toaster oven and whathaveyou at home when growing up? English muffins and French bread are a favorite pizza pasttime. I remember spooning stuff from a jar of “pizza sauce” onto halved bagels and English muffins for these after-school snack purposes growing up. Looking back, I’m not sure why the sauce should have been any different from a marinara you’d put on spaghetti. But the idea of making “pizza” at home was so captivating to a youngster that we were sold. And the idea still pulls today.
