2 x 400g cans chilli black beansor chilli kidney beans
3 tbsp chipotle chilli paste
125g self-raising flour
60g unsalted butter, cubed
70g mature cheddar, grated
1 large green jalapeño, finely sliced (optional)
Heat a glug of vegetable oil in a large flameproof casserole over a medium heat. Add the onion and a pinch of salt and cook for 7 mins until softened. Tip in the squash and sweet potato and fry for a few minutes before adding the tomatoes, beans and 250ml water. Stir through the chipotle paste and season to taste. Pop a lid on the dish and gently simmer over a low to medium heat for 25 mins or until reduced and the sweet potato is soft.
Heat the oven to 200C/180C fan/ gas 6. Mix the flour with ½ tsp salt. Add the butter and rub together with your fingers until the mixture resembles fine breadcrumbs. Stir in the grated cheddar then quickly mix in 4 tbsp cold water. Roll the mixture into eight balls. Put the dumplings on top of the stew and place, uncovered, in the oven for 15-20 mins, or until puffed up and light golden brown. Serve the stew with the sliced jalapeño scattered on top, if you like.
