Firstly peel and chop the sweet potatoes into small cubes and dice the red onion
Heat a large pot on a medium heat with olive oil and add crushed garlic, onion and spices and then fry together for a couple minutes
Then add the tinned tomatoes, black beans(drained), sweet potato, tomato puree, vegetable stock and a pinch of pepper and stir together
Bring to a boil then reduce to a low heat placing the lid on the pan for 20-25 minutes (until your desired consistency, I like mine fairly thick)
Finally, add the spinach and stir through until it wilts and it's ready to serve
