vegweb.com has TONS of recipes - I get so many of my recipes from there.
I've been a vegetarian since I was 14 (now 19), and I definately used to eat like that when I first started. Recently though, within the past year or so, I've been getting way more into veganism. I've been getting more into stirfrys and brown rice, black beans and rice (when I have hot sauce around, which hasn't been for awhile for some reason!), PB and banana sandwiches, oatmeal, pot pies, lasagna (no cheese at all), and good stuff like that. Try to help her realize that cheese shouldn't be the main staple of her diet. It's not healthy for anyone. If she doesnt like tofu, try draining it, freezing it, then thawing it. It gives it a better texture, IMO.
As a side note, even if you think that this is "just a phase", don't tell it to her. My dad is FINALLY realizing that this isn't just a phase for me. It's been really obnoxious these past five years explaining to him that I'm simply not going to eat meat again. Hah.
