I think I've solved the "vegetarian taco pasta" mystery. Forget the "vegetarian" part. It's irrelevant. Almost anything can be made meatless (except meat). The mysterious part is the "taco pasta". I bet it's just pasta with a Mexican-tasting sauce instead of Italian-tasting. Ergo, taco pasta. Tastes like a taco. Looks like spaghetti.

However, having deciphered the term's meaning does not mean I would want to eat it. My enlistment in The Legion is contingent upon an ironclad guarantee that I will not be compelled to eat vegetarian taco pasta under any circumstances short of "Eat this shit or you'll die of starvation. It's the last thing in the MRE package. You already ate the toilet paper and the wet-wipe."
