So I have been a vegetarian for about 2.5 months and so far i just have been doing stirfried vegetables and sandwiches and stuff. I work just about every night around dinner time so I am not at home to do big dinners and have leftovers for the next day for lunches. And because of my working hours I dont really eat dinner at all, maybe a snack before and after but nothing really concrete.

Question: What would be a good thing to make a healthy and providing lunch that isnt super complex?

I find i have been getting headaches and lightheadedness since I have started this diet (or only noticed it really since I have started) and so I wonder if I am not getting enough of what i should be.

Also I will be moving out in about a month, is it harder or easier to have a vegetarian diet once you buy your own groceries and such?
