This soup is best made with fresh tomatoes but you can substitute with tinned if you prefer. Bake some kale to add on top, or serve with a crusty bread roll.
Weigh and roughly chop the tomatoes, sweet potato and onion
Crush or mince the garlic clove
2. To make the soup
Use a little olive oil in a pan and cook the onion and garlic for 2–3 min

Add the water, bring to the boil then turn down the heat to simmer for 30 min or until the sweet potato is soft and breaks up; add more water if needed to keep the vegetables covered throughout cooking
3. Blend, reheat and serve
Remove from the heat and cool before using a hand blender to make a thick soup
