Chop the onion, carrot and garlic.
Heat the oil in a frying pan and gently sauté the onion and carrot for 5 minutes, then add garlic and spices.
Stir for 30 seconds, then add the tomato purée. Stir again for a few seconds, then add the wate or stock and bring to the boil.
Cover and cook for 5 minutes, then add the peas and cook for a further 5 minutes or so.
Finally, stir in the rice, and warm through.
Serve warm with plenty of freshly ground pepper and mint leaves, or other fresh herbs of your choice.
