Cut the onion into cubes and fry in a little oil. Add the curry powder and the tomatoes, bring to the boil briefly and pour in the coconut milk. Don`t forget the chilli and season with salt and pepper. Let simmer a little, meanwhile cut the meat into small pieces. Now add the pineapple pieces to the sauce and, if you like, some pineapple juice. Put in the meat and let it steep.
Rice tastes best with it.
Tip: also tastes good with crayfish instead of meat.
