Mushroom bhaji

- Wipe the mushrooms with damp kitchen paper and thickly slice.

- Heat the oil in a medium saucepan over a medium heat. Add the onion and cook, stirring frequently, for 5-6 minutes, until the onion is soft but not brown. Add the garlic purée and cook, stirring, for 2 minutes.

- Add the cumin, coriander and chili powder and cook, stirring for 1 minute. Add the mushrooms, salt and tomato purée and stir until all the ingredients are thoroughly blended.

- Sprinkle the water evenly over the mushrooms and reduce the heat to low. Cover and cook for 5 minutes, stir, then cook for another 5 minutes. The sauce should have thickened, but if appears runny, cook, uncovered, for 3-4 minutes, or until you achieve the desired consistency.

- Transfer to a serving dish, sprinkle the chives on top and serve immediately.
