The other day I went out to dinner at a nice little Turkish restaurant and one of the side to my delectable meal was some sort of wilted onion. I'm thinking it was sliced white onion wilted with white vinegar and garnished with just a tiny amount of parsley, but I'm not sure. I couldn't taste any vinegar though the onion flavor, which was dominating, but mild for an onion. I'd love to make this on my own, but I don't know where to start; any ideas or recipes would be greatly appreciated.
Oddly enough, the menu did not have any words other than the names of the dishes, and instead had images of the meals. I should have asked while I was there what the onion side was called, but unfortunately I did not.
