• 2 tsp vegetable oil
• 1 onion, diced
• 1 tbsp finely chopped fresh ginger
• 1 tbsp vegan Thai red curry paste
• 1 tsp salt

1. In a large, heavy-based saucepan, heat the oil over a medium–high heat. Add the onion and ginger and cook, stirring, for about 5 minutes or until soft.
2. Add the curry paste and salt and cook, stirring, for a further minute or so. Add the sweet potatoes, coconut milk and stock and bring to the boil. Reduce the heat to medium and simmer, uncovered, for about 20 minutes or until the sweet potatoes are soft.
