I think eggs and certain fish recipes are the primary use of non stick. But there are also ways to cook those without non stick. For scrambled eggs you can use a double boiler (you’ll never have had fluffier eggs). An extremely well seasoned carbon steal pan will also work wonders (basically what fry cooks use) For fish, cooking fish whole on a grill is amazing. Another technique with stainless pans is to get the pan searing hot first. Then add a tiny amount of oil and cook the fish and don’t touch it. This should set the surface protein quickly and create a crust that prevents sticking (requires a little practice but not too hard)
