Microwave Shepherds Pie

Put the potatoes in a lidded microwave bowl with a little water and microwave on high for ten minutes.

In the meantime, heat the oil in a large pan or wok, add the grated onion and carrot and fry for 2-3 minutes.

Add the sliced mushroom and the minced lamb and fry until the lamb is brown.

Add the wine, worcester sauce, tomato puree and rosemary and leave to simmer for 5-10 minutes, turn off the heat when the liquid has reduced to almost nothing.

Mash the potatoes with a knob of butter and two egg whites.

Put the lamb mixture into a large microwave dish. Spoon the mash on top and run a fork over the mash to make little peaks, top with the cheese.

Microwave on hire for 5 minutes. For best results also grill for 2 minutes.

Serve with mixed salad or seasonal greens. I usually make it for two and keep half in the fridge for lunch the following day.
