Skillet Baked Eggs with Spinach, Yogurt, and Chili Oil

Elevate eggs to a different realm by flavoring spinach with melted leeks and scallions, baking eggs on top, and finishing with a dollop of yogurt and a drizzle of butter spiced with a smoky Turkish chili powder known as kirmizi biber (though crushed red pepper flakes will also work). Special weekend breakfast or brunch.
