preheat the oven to 400 degrees. Line a large baking sheet with foil.
Place the bread crumbs, Parmesan, and egg white mixture in 3 shallow bowls. Dip the chicken into the Parmesan, then into the egg white, and finally into the bread crumbs. Place the chicken on the prepared baking sheet and drizzle with the oil. Bake for 10 minutes or until the chicken is cooked through and golden brown.
Meanwhile, in a large skillet, combine the wine, broth, vinegar, garlic, anchovy paste, and rosemary and bring to a boil over medium heat. Boil, stirring occasionally, until the garlic is tender and the sauce is slightly reduced, about 4 minutes. Stir in the cornstarch mixture and cook, stirring, until slightly thickened, about 1 minute. Add the parsley, stirring to combine. Add the chicken and turn to coat withthe sauce. Place the chicken on 4 plates and serve.
Helpful Hint: Anchovy paste comes in tubes, making it a convenient way to keep anchovies on hand. Keep the tube tightly capped and store in the refridgerator. Anchovy Paste will keep for 6 months or longer.
