L’Insalata Caprese (salad in the style of Capri) is a simple salad from the Italian region of Campania, made of sliced fresh buffalo mozzarella, tomatoes and basil, seasoned with salt, and olive oil. In Italy, unlike most salads, it is usually served as an antipasto (starter), not a contorno (side dish).
While it’s unknown whether the salad actually originated on Capri, it became popular after being served there to the jet-setting King Farouk of Egypt during the 1950s.
Some variations include adding chopped garlic, parsley, and various sauces. (Balsamic vinegar, Italian dressing, etc.) King Farouk reportedly enjoyed it as a sandwich filling.
