This was originally from Good Housekeeping if I recall correctly. It's really lovely and incorporates both Aubergine and Sweet Potato for a nice meal with not too many carbs:
Aubergine and Coconut Curry
Hands-on time: 15min; cooking time: 30?35min; serves 4
5-6tbsp olive oil
1 medium aubergine, cut into chunks a bit bigger than bite-sized
1 medium onion, chopped
A generous thumb-sized piece of fresh root ginger, peeled
2tbsp garam masala or mild curry paste
400g can chickpeas, drained and rinsed
1 large sweet potato, peeled and cut into bite-sized chunks
400g can chopped tomatoes
400ml can coconut milk
Small bunch of fresh coriander Small handful of fresh spinach leaves - around 125g (4oz)
150g tub Greek-style natural yogurt (optional)
1 Heat about 4tbsp of the olive oil in a large non-stick pan and fry the aubergine until golden brown and beginning to soften. Lift out on to a plate with a draining spoon, then add another 1-2tbsp olive oil to the pan and fry the onion over a medium heat for at least 10min until soft and deep golden.
2 Coarsely grate the ginger into the onion, stir for 2min, then add the garam masala. Reduce the heat a little and cook for 1-2min.
3 Add the aubergine, chickpeas, sweet potato, tomatoes and coconut milk to the pan. Bring to the boil, then simmer gently until the sweet potato is just tender - about 10-12min.
4 Taste and add seasoning. Just before eating, tear the coriander into rough pieces and stir into the curry with the spinach leaves - they'll wilt in the heat of the pan. If you want to, top with generous spoonfuls of Greek-style yogurt.
