Frittata is a dish great for mopping up those bothersome odds and ends that tend to reside in one’s fridge or pantry. Anything from leftovers to stray fungi, brassicas and lonely chunks of meat can be slung frivolously into frittata to great effect. After all, eggs and cheese go well with many types of food, such is their versatility. Eggs, in particular, have the impressive ability to be at once both happily innocuous and utterly delicious. All things considered, frittata makes a mightily frugal meal capable of transforming all manner of potential waste into something rather special.
