Place a splash of oil in a large pan and then fry the onion for at least 5 minutes, over a medium high heat, until softened. If you fry them for 15 minutes, until they start to brown, it will be even better – if you don’t have time, stick to 5 minutes.
2 tablespoon oil, 1 onion
Next add the garlic, chillies, curry leaves and mustard seeds. Keep frying for another couple of minutes, until your kitchen smells wonderfully fragrant.
3 cloves garlic, 2 finger green chillies, 1 teaspoon mustard seeds, 10 dried curry leaves
Sprinkle in the dry spices, stir well, cook for a further couple of minutes. Turn the heat down and add a tablespoon of water if it looks like the spices are sticking to the bottom of the pan.
1 teaspoon turmeric powder, 1 teaspoon garam masala, 1 teaspoon cumin powder
Add the peppers and fry for a few more minutes.
1 red pepper, 1 green pepper
Pour in the tomatoes and stock. Simmer for 10 minutes.
400 g tinned tomatoes, 200 ml vegetable stock
Finally, pop in the butter beans and stir well. Simmer for 20 minutes until the sauce is nice and thick. Serve and enjoy!
