Often a potato (in the form of french fries) is the only vegetable a lot of school-age kids eat. Of course, they often need the carbs. :^)
A long-gone restaurant near where I used to live had an appetizer, sweet potato fries, cut and cooked like french fries, and served with honey mustard and brown sugar. I used to gete that and no entree’.
My mother made the best “pommes frites” ever. She used peanut oil and some herbs I don’t remember, and sliced Maine russets. I can almost smell them decades later.
