Gruyère cheese, thinly sliced and cut into 1/2-inch strips 2 large egg whites 1/4 cup skim-milk buttermilk 1 Tbsp. Dijon mustard 2/3 cup fine, dry,unseasoned breadcrumbs 1/4 cup freshly grated Parmesan cheese, 1/2 tsp. salt 1/2 tsp. freshly ground black pepper 4 lemon wedges Preheat oven to 400 degrees F. Lightly oil a rack large enough to hold chicken breasts in a single layer. Put the rack on a baking sheet and set aside. To butterfly the chicken, place a breast half skinned-side down on a cutting board. Keeping the blade of a sharp knife parallel to the work surface, make a horizontal slit along the thinner, long edge of each breast, cutting nearly through to the opposite side. Open the breast so it forms two flaps, hinged at the center. Place one quarter of the prosciutto and Gruyère on one half of the butterflied breast, leaving a 1/2-inch space between the filling and the edge of the breast. Close the chicken carefully and set aside. Repeat with the remaining chicken breasts. In a medium-sized bowl, combine egg whites, buttermilk and mustard and beat with a whisk until creamy. In a shallow dish, stir together bread crumbs,Parmesan, salt and pepper. Carefully dip each piece of chicken in the crumb mixture and then in the egg-white mixture, and back again in the crumb mixture. Set on the prepared rack and bake for 30 to 35 minutes, until crisp and lightly browned on the outside and opaque in the center. Serve with lemon wedges. 325 Calories per serving: 40 G Protein 11.0 G Fat 14 G Carbohydrate 814 MG Sodium 97 MG Cholestrol
