Vegetable lasagna?

Your recipe sounds good to me, have you got any mushrooms, courgette (zucchini) etc you could add? Remember to cook your roux well, don't want it tasting of raw flour. Regarding the quantities, it really depends on the size of the dish you plan to cook it in, I normally do things by sight anyway and hope for the best. p.s, email me some over please, I love lasagna.
