The previous poster makes some excellent points. Try simple additions at first. Baby carrots as a snack, bananas, apples. These items require no preparation and are relatively inexpensive. Once you're in the habit of snacking on fruits and veggies, try and incorporate them more in your meals and experiment with new/different items. I used to think making a salad was a chore but now it takes me less than a minute to whip one up to go along with my dinner.
