TASTY, quick, desirable health food?

I'm looking to replace some of the junk in my cabinets. I'm not a veggie hater and I don't mind healthy foods, it's just so hard to choose those things over the obviously much better tasting, much more fattening foods. And it's even more difficult to get my boyfriend to enjoy healthy foods. The only thing he really likes and will eat regularly that's healthy is cottage cheese. We've been together for about 2 years now and living together pretty much the entire time... needless to say we've both gotten way too comfortable and have gained some excess weight.

So I'm looking for some healthier options that are really CRAVABLE. Things I can really be jonesing for when I'm just looking to munch on something at night. Quick healthy meals to make that don't take a lot of preparation, and ones that do as well. But mostly grab-n-go foods, it seems it's almost impossible to find something smart to eat that's tasty and satisfying and ready to eat!

So suggestions are appreciated. :) Especially suggestions of those foods that will make it a lot easier for the pounds to shed!
