pounds boneless skinless chicken breast cut into 4-ounce pieces
Salt and pepper
tablespoon chopped sage, plus 24 large sage leaves
garlic cloves smashed to a paste
pinch red pepper flakes, optional
thin slices prosciutto
slices fontina cheese (about 4 ounces)
Using a meat mallet, pound the chicken to flatten a bit. Salt and pepper each piece on both sides and place on a platter. Sprinkle with chopped sage, garlic, red pepper flakes (if using) and olive oil. Massage in the seasoning to distribute, cover and marinate at room temperature for one hour, or refrigerate for up to several hours. Heat a wide skillet over medium heat and add 3 tablespoons olive oil. When the oil looks wavy, add the sage leaves and let them crisp for about 30 seconds. Remove and drain. Brown the chicken breasts in the oil for about 2 minutes per side, then transfer to a baking dish large enough to fit them in one layer. Top each piece with 2 sage leaves, a slice of prosciutto and a slice of fontina. Broil for 2 to 3 minutes, until the cheese is bubbling. Garnish with remaining sage leaves.
