Heat oven to 180C/160C fan/gas 4. Heat 1 tbsp of the oil in a frying pan. Cook the onion and mince for about 5 mins until the meat is browned. Stir in the garlic, curry powder, sweet potato and 300ml water. Cook for 5-8 mins until the potato has softened. Stir in the peas, coriander and a squeeze of lemon juice, then season.
