How to Make It
Preheat oven to 450°.
Place slice of bread in a food processor, and pulse 10 times or until coarse crumbs measure 1/4 cup. Combine the breadcrumbs, 1/4 cup chopped parsley, cheese, and 2 teaspoons thyme in a shallow dish. Sprinkle pork with salt and pepper. Combine Dijon mustard, fennel seeds, and garlic in a small bowl. Rub pork with mustard mixture, and dredge in breadcrumb mixture.
Place the pork on a jelly-roll pan coated with cooking spray. Bake at 450° for 25 minutes or until a thermometer registers 160° (slightly pink). Let stand for 10 minutes. Cut crosswise into 1/4-inch-thick slices.
Substitute Parmigiano-Reggiano for the Romano cheese or try honey mustard in place of Dijon mustard, if you prefer.
