Is a hot-dog filling

Answer 1

I would describe it as a snack rather than a meal. Therefore the answer must be - no.

It depends on whether or not you are a big eater, and the size of the hot dog, and what you put on it. For example, in the southern U.S., Hot Dogs are often eating with chili, slaw, mustard and onions, and one can be filling to a person that is not a big eater, or a child. There are way too many variables here.
