Frittata al tartufo is a traditional Umbrian and Istrian dish made with a combination of eggs, black truffles, olive oil, salt, and black pepper. This simple dish is made by pouring beaten eggs into a pan with hot olive oil, and then adding thin shavings of truffles, salt, and pepper to the pan.

After the eggs have curdled, all that's left is to sprinkle the dish with finely chopped parsley or dry white wine before serving. If desired, the dish can be additionally flavored with grated cheese on top. In Istria, the dish is called fritaja s tartufima - it's commonly prepared for breakfast and it can easily be found in local restaurants. 

Frittata di zucchine is a traditional Italian egg-based dish originating from Tuscany. The dish is usually made with a combination of eggs, thin slices of zucchini, olive oil, salt, pepper, sage, and minced parsley. The zucchini slices are cooked in olive oil over high heat until soft and golden.

The heat is reduced, and the mixture of beaten eggs, parsley, sage, salt, and pepper is then poured into the pan and cooked until the frittata is golden brown on both sides. Once done, frittata di zucchine is served warm.

Deviled eggs typically consist of shelled and halved hard-boiled eggs that have had their boiled yolks removed and blended with ingredients such as mayonnaise, mustard, pickle relish, and seasonings into a smooth paste, which is then added back to the cavities of the egg whites.

This all-time favorite is usually finished with paprika on top, and it is typically enjoyed chilled either as an appetizer or a side. Often mistakenly considered an American culinary contribution, the first versions of this simple gourmet delicacy are believed to have been invented in ancient Rome. 

Frittata is a traditional Italian flat and round egg-based dish that's closer to a Spanish tortilla than to a French omelette. It's made with a combination of whisked eggs and additional ingredients such as prosciutto (crudo or cotto), grated cheese, or sautéed onions.

The frittata should be completely set, yet moist. The eggs should be beaten lightly so that the air bubbles don't form. The egg mixture is traditionally cooked in butter or a mix of butter and oil. When the butter or oil begin to foam, the mixture is cooked slowly over low heat, usually in a heavy-bottomed frying pan.
