<human>:  Why is it called a Caesar salad?
<bot>: It’s named after Caesar Cardini, a chef who invented the salad in 1924. It’s a classic salad made of romaine lettuce, parmesan cheese, and croutons, with a dressing made of egg yolk, lemon juice, and garlic. The dressing is what makes it a Caesar salad, not the lettuce or croutons.
