Walnut-Stuffed Chicken Roulades by Walnut-Stuffed Chicken Roulades Skinless chicken breasts are a great source of protein: With about 40 grams in a six-ounce portion, they're on par with beef, yet far leaner: They have approximately five grams of fat and are, of course, carb-free. No skin doesn't have to mean no flavor, however. Whole-grain crackers and walnuts make a great substitute for traditional breadcrumbs, while mushrooms and spinach can provide a delicious, hearty stuffing.
