Freezing Question

[catsrcool]

I am making a batch of Cannelloni and a batch of Lasagne using these two recipes:

I want to freeze them. Shall I cook them then freeze them or assemble them and freeze uncooked?

Cook and then freeze. (Some of the ingredients, such as celery and mushrooms, don't freeze very well in their raw state).

Thank you I was wondering what would happen to the veg if it was frozen before cooking.
