I have some friends coming for tea tomorrow night who we havent seen for years. The girl is Lactose intollerant, so i want to cook them tea but want to make a nice dish that is lactose free. I am hoping I can make a lasagna, i will make a normal one for us but a special one for her. I am planning on using zymil milk in the bechamel sauce and hoping my supermarket will have a lactose free cheese option.

Does this sound ok, or am I missing something? Sorry for sounding ignorant
