my dining hall served this sorta thing a bunch. "glazed sweet potatoes" or "glazed acorn squash." i liked it a lot, but i treated it as a cheat food/dessert. it's just some sort of sugary sauce. probably brown sugar or something.
i've got a weakness for sweet potatoes though, so turning these down was rough. that dish reminds me of thanksgiving. i can't wait until that holiday. back when i was vegetarian, i enjoyed it more than the turkey eaters just because i would be entitled to as much of the sweet potato dish as i pleased....the rise of the insulin junkie....
