Warming, nutritious and so so good - that's what this curry is. As with all the curries you can basically make it your own by changing butter beans to chickpeas or adding some other veggies or make it non vegan and add beef.
Heat the oil in the frying pan. Chop the onion and garlic and sweat in the oil on low heat.
Add curry paste and fry for another minute.
Drain the beans and add to the pan.
Add tomatoes and water. Cover and simmer for 20 minutes until tomatoes dissolve to a smooth sauce.
Season to taste. Add chilli, depending how hot you want the curry to be and then add the Worcestershire sauce.
As the last step, add spinach and mix. Turn the heat off so the spinach doesn't over cook.
I like to serve it with either quinoa or millet.
