We're vegetarian and I do a lot of cooking. Some of the things I like from TJ's are their refrigerated ravioli, frozen burritos (especially the vegetable ones), and a lot of their frozen veggie mixes. They have a roasted vegetable mix with beans and mushrooms in butter that is really good especially with some bread for dipping in the butter sauce. Serve it with something easy but healthy and it balances out. TJ's has a lot of Italian dishes, but they're high in sodium and heavy on cheese.
Whole Foods often has grilled tofu squares on their salad bar. I'll pick those up on occasion because then it's already cooked and you can just toss it into your stir fry or add it to something else really simple.
Both places have good vegetarian soups. Get the kind in the cartons. Pick up the bake at home ciabatta rolls from TJ's and put them in the freezer so you can bake them on one of the quick fix nights.
I got a vegetarian slow cooker cookbook last year and really like it. Most meals take about 5-10 minutes to prep in the morning and you are guaranteed to have leftovers. This is the one I bought
