Step 1

Half-fill a saucepan with cold water and add the potatoes and carrots. Bring to the boil and cook for 8 minutes. Add the cauliflower florets and cook for 2 minutes more. Drain in a colander and set aside.

Step 2

Heat the oil in a large, non-stick frying pan or wide-based saucepan. Add the onion and cook over a medium heat for 8 minutes or until well softened and lightly browned, stirring regularly. Sprinkle over the curry powder and cook for 30 seconds more, stirring.

Step 3

Add the tomatoes to the onions and cook for 2–3 minutes, stirring constantly. Add the stock and bring to a gentle simmer. Add the vegetables and peas or spinach and simmer gently for 5 minutes, stirring regularly. If the sauce thickens too much, add a splash of water.

Step 4

Serve immediately with yoghurt and mango chutney.
