Looking at poll results, I gotcher wife's back. Eggplant is excellent if properly prepared. If you screw up, it's bitter and tough.
Mash a bunch of garlic into some olive oil and let it sit for an hour or so.
Cut an eggplant into long slices, 3/8 to 1/2" thick.
Brush both sides of slices with the garlive oil, mebbe grind some pepper on, put on a cookie sheet, broil for five minutes.
Brush, turn slices, broil until tender.
I like it. Grilled, parmagiana, mashed into a dip for pita chips, grilled in a salad with goat cheese (ok, I said I liked it). As for nutritional value, it's actually quite low in Saturated Fat, Cholesterol and Sodium and contains a fair amount of fiber with some protein too. I do agree that if it isn't cooked right, it's pretty awful.
Nah its pretty low in nutritional value (ie there is nothing in it) for a vegetable even in its raw form before you cook it and it loses nutrients. Its got decent fiber, some minerals and some vitamins but its not a nutritional all-star of the vegetable family. I still like it prepared right and its a lot better than nothing food like iceberg lettuce...
