I also do a lot of grilled veggies during the week. Marinate them in ff italian dressing during the day and grill when you get home (or roast in the oven if it's not too hot out). Very quick and yummy! I always make extra, and throw some in a container to eat with lunch the next day.

I also do the chop veggies on the weekend trick. I even bag them individually so that when I'm putting together food for the day during the week, I can just grab and go.
