I don't usually add anything to the kibble itself (except sometimes water) but I do often feed raw meats for one of her meals and she really enjoys it. I wouldn't bother with the green beans/pumpkin, etc since dogs don't really need any plant material and they already get plenty from any kibble. I feed a raw egg about once a week and usually whenever we cook meat I'll save a raw piece and give it to her for dinner...chicken, beef, pork etc.
