It's just a big fat purple thing you can eat. No flavour and the bastard doesn't even have the decency to contain any vitamins or anything. Having said that, the missus eats them all the time but, then again, she's a vegetarian and so clearly isn't too worried about flavour, protein, etc.
Melanzane alla parmigiana - great if you've got vegetable people coming to dinner.
Slace, salt, wash, dry and fry the aubergines, then layer them in a dish with a nice rich tomato-onion-basil sauce, put some grated Parmesan (the fresh stuff that smells of schoolgirl changing-rooms, not the pre-grated filth in a box that smells like Satan's dirty sock bag with white-cider-puke mixed in) between each layer, then put some fresh Buffalo Mozzarella on top, bake for about 30 mins at 180.
Vegetarian nosh that normal people can eat without nipping into the kitchen for a sustaining meat pie halfway through.
Cook as above then layer them in a dish with chili and garlic. Splash a bit of olive oil on it all, cover and keep in the fridge. When needed, chuck a couple on toast with a fried egg or savoury mince on top. You can also try curried brawn microwaved for 30 seconds to turn it into a rich gravy.
Most of these suggestions sound like they just about prevent you from throwing them things back up! Indian (mogul) cooking really works and I swear I did not know what I was eating when trying Bahrta for the first few times, I hate aubergines!
