Preheat frying pan over medium heat. Wrap each chicken breast in a piece of prosciutto.
Pan sear two or three pieces at a time until golden.
Transfer to a large baking dish. Top with the sliced mozzarella. Bake for 30 minutes or until the chicken reads 160 degrees when checked with a meat thermometer.
Meanwhile, deglaze the frying pan with the chicken broth. Just add the broth and garlic to the pan and turn up the heat. Scrap any browned bits off the bottom. They give the sauce tons of flavor. Mix the glucomannan into the lemon juice and add that to the frying pan. Cook until slightly thickened. Turn to very low. Stir in the salt.
When the chicken is cooked through spoon the sauce on top of it and serve.
