Thai curry. Can be with chicken, fish or vegetables.
Thai green curry paste, onions, garlic, extra chillies (if you want) lemon grass, kaffir lime leaves (you can get freeze dried in s'markets), tin of coconut milk, but the best ingredient in my opinion is the butternut squash, adds lovely texture and everyone has been impressed.
Fry onions, add paste fry for a bit, add ginger, garlic, chillies, fry for a bit, add half tin of coconut milk (the solid part, don't shake it), lime leaves, bash lemon grass and add, wait until coc milk has released some oil and then bung in chicken or whatever and cook, add rest of coc milk at end and heat up. You can add another tin of coc milk if not enough liq or some stock if you prefer.
