For such a simple recipe, this dish looks lovely and impressive. It delivers a crispy-crunchy crust, creamy herbed cheese flavor, and plenty of earthy fresh spinach. The eggs add satisfying richness, and the runny yolks provide a luscious “sauce” to swipe the crust through. Look for artisan flatbreads near the naan, pita, and other flatbread options in your grocery store. Be sure to line your sheet pan with foil or parchment paper as directed so that if any egg runs off, it doesn’t scorch the pan.
