This menu sounds absolutely brilliant, and delicious. I think it's so sweet of you to be taking her into account in this way - particularly the thought of wanting her to have 2 options for dinner. As a vegetarian myself, I'm touched when people choose to make sure there's even one entree so I don't have to make a dinner entirely of sides. When someone makes sure I actually have *options*..... oh, dear, that's just very very wonderful of you.
That's the thing I miss the most about being a vegetarian I think - having options. In a really really high proportion of holiday meals, catered meals, meals at parties - there's exactly one thing I can eat. Even at a lot of restaurants, I'm quite accustomed to searching the menu for my single option - and that's dinner, whether it sounds particularly appetizing or not.
The idea of having options is just LOVELY!
BTW, there is a AWESOME LOOKING butternut squash and goat cheese and sage lasagna in the most recent issue of Fine Cooking magazine, if you didn't want to do just a cheese lasagna. (Recipe calls for freshmade pasta sheets, but I'm sure that's not necessary.)
