👉 A Campanino is a type of pizza, typically made with an omelette, served on a thin slice of bread. It's often referred to as "the" version of the classic American dish because it originated in Italy and has become popular worldwide. A typical Campanino consists of a mozzarella cheese, a tomato sauce, diced onions, bell peppers, mushrooms, spinach, and sometimes other vegetables like zucchini or eggplant.
