I think I'd just go buy them instead of make them
I'm not sure why Sonic's favorite food is chili dogs, but whatever. Rosanna Pansino, star of my favorite videogame cooking show Nerdy Nummies, has created a Sonic-themed meal here in the form of Sonic chili dogs with onion rings.
I guess the reason it's Sonic-related is because, like the hedgehog, you'll be thinking (and probably saying) "Gotta go fast!" a whole lot after eating this meal.
