I grow several plants of the big black eggplant..usually Ebony "XXX" depending on where you get them, plus a couple of the small, long and sometimes a few purple white Italian ones. I absolutely love eggplant parm! Actually, I rarely soak mine, or peel. Never felt the skin bitter or tough. I also cube & cook in olive oil with oregano & garlic. YUM!
I slice, saute and freeze. Then use for eggplant parm, or cubed in spaghetti sauce over pasta
Yep, pizza with them as FEM describes is good, quick and excellent for you. They make a great salad if lightly sauted in olive oil, cooled and added to tomato, onion and Italian spices. Also, slice, oil and grill.
