Now she could have introduced a vegan menu in a more palatable way, have it as an option ( but not the whole menu, take consideration of the nation they are from and have that as the centre piece. Also not to forget to represent the traditional and popular of your country too) and explain to them how due to her background in the temple she has turned more appreciative of what she puts in her body, reference any medical benefits she could think of about it and actually have a great chef who is good at it make the menu and last but not the least don't force the other party into it and let them make their own decision.
