My best hint would be to spend a few hours on the weekend slicing, dicing, etc. all of your fresh veggies and prepare some brown rice and whole wheat pasta. Put the veggies in ziplock bags with a paper towel and put all the little bags in your crisper in the frig. Put the rice and pasta in containers in the frig. Here you are all prepared for some great stir-frys. My suggestions on veggies would be red bell pepper, celery, broccoli, cauliflower, cabbage, asparagus. I would cut the onion and tomatoes as i used them (the cut onion can really smell up your frig - ask me how i know).
I also prepare my salads on the weekend. Using the salad spinner to remove excess moisture and placing a paper towel in the ziplock bag. The salads will last for many days when prepared this way.
So there you have some great meals that you can prepare in less than 15 minutes will all of the prep work done.
