Some suggestions are Wellness Mixers & Toppers, they are pure pureed meat like turkey, chicken, lamb or beef and are intended to be topped or mixed in foods, though work good as a training treat in little bits. PetSmart should carry them. Chicken broth that's low/no fat/sodium is also another option. Like others say, a bit of Parmesan or yogurt for flavor. A little cottage cheese is another decent suggestion.
