Frittata di Verdura

The quantity of vegetable to egg varies enormously, depending upon which kind of vegetable you are using. The basic rule of thumb is that there has to be enough egg to hold the whole dish together, but there must be enough vegetable content for the vegetable to form the main part of the finished dish. I tend to use about two thirds vegetable and one third eggs. Be very careful not to add too much cheese, as this will cause the frittata to stick and make it impossible to turn over successful
