This is the recipe I use, below. you can do all sorts with it really, stuff naans with it, wrap it up in tortillas, or even hollow out aubergines, grill them and put it it in that.
3 tbsp corn oil
2 med onions
2 tsp ground cumin
1 tbsp ground coriander
2 cloves garlic, minced
2tbsp fresh minced ginger
4 tbsp natural yoghurt
2lb lamb mince
1/2 tsp turmeric
1/2 tsp cayenne pepper
1.5 tsp salt
heat oil, fry onions for 6-7 mins til browned. Add the cumin and coriander, and stir til coated. add the ginger and garlic, fry for a min. Reduce the heat and add the yoghurt, a tbsp at a time until it is absorbed. turn heat back up and add the meat, turmeric and cayenne pepper, stir and cook for about 5 mins. add about 2 cups of water, salt and the peas, and simmer gently for about 20 mins.
add finely chopped green chillis, garamasala, mint and coriander to garnish to taste. cook for further 10 mins. The water should be absorbed, but don't let it dry out completely.
