The term 'burger side' refers to the accompaniments that are typically served alongside a hamburger. The most common burger sides are FRIES (5 letters), slaw (4 letters) and onion rings (10 letters). FRIES are thin strips of potato that are deep-fried until golden and crispy. Slaw is a type of salad made from shredded cabbage, carrots and other vegetables, usually dressed with a mayonnaise-based sauce. Onion rings are rings of onion that are battered and deep-fried. All three of these sides are popular accompaniments to hamburgers.
