You mentioned burritos and pasta for dinners. How about diced tomatoes and spinach in your burritos? For the pasta, how about throwing in some broccoli florets and/or making a nice sauce with fresh tomatoes and basil?
Oooo! You just reminded me that I have a recipe for broccoli and spinach enchiladas that is to die for! Assemble ahead of time + pop in oven before taking post-commute shower = hot, fast dinner with almost no work.
