I need to know some good affordable vegan/vegetarian food pleaseee(:?

I'm a 19 year old girl from Chicago and i recently became a vegetarian for health/moral reasons. i'm looking for suggestions for good filling veggie meals. i'm pretty used to lean cuisine and healthy choice, but most of their good stuff has meat in it. i know that there are tons of options for vegetarians these days and i have access to Whole Foods, Trader Joes and Fresh Market, all the best supermarkets, but they're kinda expensive and usually don't have instant meals. i go to college full time, work part time and have a long distance fiance who's deployed with the marine corps in afghanistan so i have almost no time for myself haha. i have a good enough budget and i just need a little help. thanks!(:
