Frittatas are often prepared in well-seasoned cast iron skillets or other non-stick ovenproof pans or cookware. However, a standard 10” non-stick skillet will also work provided you don’t try to pop it in the oven! This savory stovetop frittata is easy to make and really versatile. The most difficult part is deciding whether you should enjoy it for breakfast, brunch, lunch, or dinner.
