Whichever the place (restaurant, dinner at a friend's...) we would say it for example about the vegetable you find in couscous, spiced with harissa sauce.
I would understand if one were talking about salsa or hot sauce but how would one know that the strength of vegetables refers to them being spicy?
no spicy sauce is mentioned but what else? you can't expect vegetables to be muscular, can you?
couldn't "the vegetables are bright" be a valid translation as well? I put that and it marked it wrong.
No, because "fort" related to food is about taste (probably a hot spicy sauce was poured on them)
Yes, in most cases. It can also be the very taste of the vegetable that is "fort" like peppery, prickly, pungent, tangy, sour, biting, bitter...
Smells and scents can be "forts" as well.
