A Caesar salad is a salad of romaine lettuce and croutons dressed with parmesan cheese, lemon juice, olive oil, egg, Worcestershire sauce, garlic, and black pepper.

The salad's creation is generally attributed to restaurateur Caesar Cardini, an Italian immigrant who operated restaurants in Mexico and the United States. Cardini was living in San Diego but also working in Tijuana where he avoided the restrictions of Prohibition.
