Titsalinabumsquash aubergines are one of my favourites. Cut little slits in and stuff slivers of garlic in. Pour over olive oil and roast till soft. Can do this on the BBQ too (wrap in foil) Eat with cheese crisps like a dip.
Slice up and roast with lots of olive oil and a few shallots and cherry toms until golden brown. Use to top a big salad with cider vinegar / olive oil dressing.
Or roast slices until crisp (ish) and use to scoop up baked feta (half a block of feta topped with olive oil, chopped shallot, chopped tomato, oregano and wrapped in a foil parcel and baked in the over for 25 mins) works great in the BBQ too!
Half an aubergine and score flesh. Pour over olive oil. Roast till soft. Scoop out flesh and stuff. You can stuff with lots of different things but my favourite is chorizo.
I fry some chorizo, mushrooms, shallots with garlic and smoked paprika. Then add in spinach until wilted and finally some cream cheese. Pop filling in halfway and top with Parmesan. Bake until golden.
Aubergine parmigiana is lovely too but a bit higher as has quite a bit of tomato.
Slice oil and griddle the aubergine (good mixed with courgettes too)
Layer with a hm tomato sauce (passata reduced with oregano, garlic and basil until thick) and fresh mozzarella and Parmesan. Bake until golden and bubbling.
