Mushroom Lasagna

We hosted my husbands family for a games afternoon on Sunday.  He is one of 5 siblings and they all enjoy playing games and each others company, so we try to bring the family together a few times a year to do this.  I decided to cook lasagna as it is easy to cook for a crowd and who doesn't love lasagna.  My Sister in law however is vegetarian and so I try to make some main course that she can eat, and decided to make a vegetarian lasagna.

It turned out to be a good job as my nieces husband had also given up eating meat for lent!

This made enough for 4 if that was all you were having

1 onion finely chopped
2 cloves of garlic sliced
2 tablespoons of olive oil
6 cups of mushrooms chopped
2 cups of white sauce (see below
lasagna noodles (preferably the oven ready ones)
1/2 cup of ricotta cheese
1 cup of grated mozzarella cheese.

White sauce
2 tablespoons of butter
2 tablespoons of flour
2 cups of milk
1/2 cup of grated Parmesan

Put the butter in a large microwavable bowl and microwave for one minute.
Add the flour stir and microwave for one minute
Add the milk and using a whisk mix together microwave for 2 minutes
Whisk again and microwave for a further 2 minutes.
The sauce should now be thickened, but if not whisk again and microwave for a further minute.
When the sauce is the required consistency add the Parmesan cheese and mix well.

Add the olive oil, onion and garlic in to a large pot and cook until the onion is translucent.

Then add the chopped mushrooms.
