How to Make It
Preheat oven to 350°.
Place turkey tenderloins in an 8-inch square baking dish; rub with oil. Sprinkle tenderloins evenly with Italian seasoning, salt, and pepper. Pour 1 cup chicken broth into dish. Bake, uncovered, at 350° for 35 to 40 minutes or until a thermometer registers 170°. Let stand 10 minutes.
While turkey stands, place remaining 1/4 cup broth, mayonnaise, and next 5 ingredients in a food processor; process until smooth. Remove turkey from dish; discard broth. Cut tenderloins diagonally into 1-inch-thick medallions. Spoon sauce over sliced turkey, and sprinkle with parsley. Serve warm.
Tonnato (tohn-NAH-toh) means "tuna sauce" in Italian.
