Hi Sandy-
It is sooo hard to eat well when you're busy, but if you are willing to spend a bit of time prepping (say an hour at most) on Sunday - you can really help yourself out during the week.
BF and I are fairly healthy eaters, and neither of us have lots of time. We go grocery shopping on Sunday morning (before the produce has been picked over) and stock up on the best looking veggies and fruits - to make salads with.
We get the big sized box of Spring Mix (or baby spinach when it won't threaten our intestinal system). If you want to be extra careful, you can rinse it, but we get the Organic kind that says it's triple washed already.
The fruit we pick out (lately it's been strawberries, rasberries, blackberries and/or blueberries) gets put into individual paper-towel lined bowls right away b/c the produce guy told us that is how they keep longest.
The veggies all get cleaned and cut up into bite-size pieces (when necessary) and put into small tupperware containers. These usually include cucumbers, peppers, celery, grape tomatoes (already small enough), sugar snap peas, shredded carrot....you can pretty much put anything in a salad I think.
In the mornings, before work, first person up gets the containers out of the fridge and sets them on the counter. It's basically like having an at home salad bar. We also buy the golden raisins, and lightly salted cashew halves to sprinkle on top. I don't really use salad dressing, but BF brings a bottle to work and leaves it there.
I eat a lot of trail mix. Keeps me satisfied, it's very portable, and I feel better eating natural foods. I also don't have that sugar crash that can come from other snack-type foods. Lara bars are good to keep around b/c they are pure food as well. No added sugar or flour or any of that other crap.
Also, check out Costco for the bag of Frozen Salmon Burgers. They are mostly Salmon, not breadcrumbs and stuff, and you can cook them in the oven from frozen. 9 min per side. You can make sandwiches, or cut them up to put in salad or pasta. Cooking isn't so bad when you just have to put something in the oven. Make a whole box of whole wheat pasta (wheat fills you up more - and keeps you full longer) and put it in a tupperware. Throw a box or bag of veggies in the microwave to steam them. Keep some good jar'd pasta sauce around. You can mix the sauce, the veggies, and the cut up salmon burger - and put them over the pasta. maybe add some lowfat shredded cheese on top.
A good standby is the frozen, ultra-thin crust pizza. We like Palermo'shttp://www.palermospizza.com/Default.aspx?bFlashFound=1
The Margherita (tomatoes garlic basil) is our favorite. The thin crust makes it lower in calories.
I could go on forever, but this is long already.
Lastly - if you are getting chinese food - order your meal with the sauce on the side. I've never had a problem when I've ordered it like this, and you end up getting a steamed dish of protein and veggies. Order brown rice whenever possible. It will also fill you up faster, leaving some for leftovers.

I love finding new ways to eat healthy and conveniently.
I hope some of this info helps - Good Luck!!
