Peel and dice the sweet potatoes. Finely chop the onion, garlic and ginger.
Heat the olive oil in a large pan and cook the onion, garlic and ginger gently until soft and translucent. Toast the cumin and chilli flakes briefly until fragrant.
Add the sweet potatoes and sweat them briefly. Pour in the tomatoes and vegetable stock, bring to the boil, then simmer gently until the sweet potatoes are soft.
Stir in the peanut butter until the stew turns creamy. Fold in the spinach and let it wilt.
Season to taste with sea salt and adjust the consistency with a little stock if needed.
Ladle into deep bowls and serve with chopped peanuts and fresh coriander if you like.
Good to know
This stew is warm, creamy and pleasantly spicy. It's little effort but tastes of lots of cooking and time. On days when you want something hearty, it's just right.
