The onion rings are very popular snacks, that are usually added in or by the side of a burger. Let’s find out more about the onion rings! While typically served as a side dish, onion rings are often eaten by themselves. The Animated Series, Spaceballs, produced an episode called “Lord of the Onion Rings.” It was a parody of Lord of the Rings in which Barf finds the One Onion Ring stuck in an old couch inside the Eagle 5. Onion rings are (very) often eaten with burgers.
