Turnip greens (at least the ones from my garden) are not bitter. They are not palatable fresh (such as spinach) due to prickly fuzz, but blanched they are delightful. I have had success feeding them to my children by chopping them up (about 1/2 inch diced, thick stem parts removed) along with some carrots, celery and onions. Brown rice and chicken stock make a good addition as well with said veggies. If I told them to eat their turnip greens (alone), they might just turn up their noses! For 'non greens' eaters, the trick is to not overpower them by eating all greens. Moderation is a good thing. Are you a 'greens' eater? If so, care to share a quick fix?
