Chicken 555 is a popular, spicy South Indian appetizer of deep-fried, crispy chicken strips tossed in a flavorful sauce made with chili, garlic, ginger, and aromatic spices like curry leaves, often served as a starter or snack. It's known for its crunchy texture and tangy, spicy taste, similar to Chicken 65 but with its own distinct flavor profile, and can be served dry.
