there's a one-pot recipe from the first archie comic.

i think i confused the chili-only recipe from the cookbook as a separate chili dog recipe. so there are basically two recipes.

including sonic r. i literally started off with sonic r as a kid

the cookbook has chili dog recipes for shadow, silver, big the cat (with tuna salad) and eggman (being the more bougie one), so we have more than just soncic

oh, and sonic runners has a cutscene where sonic wanted to give a chili dog to the little pig guy (picky) as a gift or something, but omochao told sonic "no no that's not appropriate for pigs" so there's a bit of canon showing the chili dogs are not vegan in the slightest
