I don't even think of onions and garlic as vegetables; they're so vital to the taste of just about any savory dish that they're a given. I think about onions and garlic the way a fish thinks about water.
I like:
Asparagus, Brussels sprouts, Cabbage, Daikon radishes, Eggplant...heh, I really could carry that list out to Zucchini! I'm happy that my list of oogy vegetables is shorter than the list of yummy ones.
Oogy vegetables: mushrooms, raw celery, canned beets.
