Going veg, you want to make sure that you get enough protein in your diet, if you pass on tofu, I'd go for lots of beans - Lentils make for a nice substitute- (somewhere in tilted cooking there's a recipe for lentil loaf that's quite good...
(Tip on beans: if you are going for dried beans, trhow out the soaking water and the bean after effects, diminish greatly...)
At your local library, or bookstore- check out the
Moosewood Cafe Cookbooks. The Moosewood cafe is a purely veg restaurant in upstate ny - the cookbooks are a fun read... and have great recipes... The
Moosewood Cafe Recipes are also good... and adaptable..
For simple lunches to take- I'd probably go with a simple wrap -- with Hummus (an easy to make ground garbonzo bean, garlic, lemon, and tahini spread) with some of your favorite vegetables... Tabouleh is something else I like a lot... or if you like eggplant... just a roasted eggplant with some olive oil and sun dried tomatoes if you please... all on pita bread... (I'm a big fan of the dippable lunches)

sushi The rice is easy to cook, and easy to find, the nori, should be pretty easy to find as is the bamboo rolling mat... then you are just limited to your imagination as to what to stuff the sushi rolls with..
