This being said, the word "vegan" is not properly used here, causing confusion. "Vegan" relates to diets and food in general according to the dictionary. The author probably simply meant "plant based" and erroneously used "vegan" instead. Unless they meant it's a dish in which case... yeah, I guess.

It’s also used to talk about things like clothing made out of leather alternative.

I imagine that's also used erroneously. It may make it into the dictionary with this meaning at some point but right now people just ad-hoc borrowed the diet/food-related term "vegan" and apply it for things that use no animal products. Now imagine if someone called coal a "vegan energy source". :)
