1. preheat the oven to 180C/350F/Gas 4.
2. First cook the lasagne. Then drain and rinse in cold water.
3. Gently fry the finely chopped onion in the oil for a few minutes to seal in the flavour. Add the mushrooms and courgetted and fry for a few minutes until softened. Add the oregano, tomatoes and tomato purée. Cover the pan and cook for 10 - 15 minutes so that the flavours have a chance to blend. Then season to taste.

5. Bring it to the boil, stirring constantly and cook for 5 minutes over a gentle heat.
6. Then add the cream and cook gently for another minute.

8. Repeat these layers ending with a layer of cream sauce.
9. Cover with grated cheese and bake for 35 - 40 minutes when the cheese should be bubbling and golden.
