I think I nabbed this recipe from someone on BB actually, pretty much word for word. Please claim if it's yours, because it's the easiest most delicious thing I've ever eaten.

Dahl soup

2 tbspn butter
2 cloves crushed garlic
1 tsp grated ginger
1 chopped onion
1/2 tsp turmeric
1 tsp garam masala
1/4 tsp chilli powder
1 tsp ground cumin
1kg canned chopped tomatoes
1 cup red lentils
2 tsp lemon juice
600ml vegetable or chicken stock
300ml coconut milk
1 bunch chopped coriander

Melt the butter, add garlic, ginger and onion and saute, stirring constantly, until onion is translucent but not brown
Add turmeric, garam masala, chilli powder & cumin and cook for 30 seconds to release the spices
Stir in tomatoes, red lentils, lemon juice, stock and coconut milk and bring to the boil
Reduce the heat and simmer uncovered for approx 30 mins until the lentils are tender
Add the coriander and season to taste

If you fancy a Malaysian twist to it you can use lime instead of lemon juice and add a tablespoon of peanut butter too
