Sonic's favorite food is chili dogs. This trait was first introduced in the 1993 animated series "Adventures of Sonic the Hedgehog" and was later officially incorporated into the video game series starting with Sonic Chronicles: The Dark Brotherhood. Before the first appearance of the chili dog in the series however, Sonic's enjoyment of hot dogs in general was first established in Issue #5 of "Sonic the Comic", in a scene where Sonic is seen ready to eat three hundred hot dogs as a part of his breakfast. Since then, the chili dog has been established as Sonic's favorite food in almost every piece of Sonic media (for context, the only show to not reference chili dogs was "Sonic X", and even then a normal hot dog appeared in the episode "How to Catch a Hedgehog" during a scene where Sonic is stuck running in a giant hamster wheel), eventually making its way into the games as well, a rare example of something originating from the cartoons/comics being carried over into the mainline games.
