Greek King Prawns Baked with Feta

Prepare the prawns:
If frozen thaw slowly in the refrigerator. Twist off their heads and peel off most of the shell leaving a small piece of the tail intact. Slit down the back of each prawn with a sharp knife and extract the vein. Rinse and pat dry with kitchen paper.

Pour the oil into a large saucepan, add the onion and cook gently until tender. Add the garlic and cook until lightly golden. Add the tomatoes, bring to the boil and simmer gently for 30 minutes. The sauce may be prepared several hours ahead to this point.

When ready to cook reheat the sauce, add the prawns, stir gently and transfer to an ovenproof dish. Crumble the feta over the top and bake for 12 minutes in an oven preheated to 350°F/gas mark 4/180°C or until the feta is lightly coloured and the prawns are cooked through. Serve hot.
