Pork Tenderloin Florentine

Directions

1. Cut a lengthwise slit down the center of the tenderloin to within 1/2 in. of bottom. Open tenderloin so it lies flat; cover with plastic wrap. Flatten with the flat side of a meat mallet or rolling pin to 1/4-in. thickness. Remove plastic and sprinkle meat with garlic powder; set aside.
2. Separate caps from stems of three mushrooms; set caps aside. Chop stems and remaining mushrooms to measure 1/2 cup. In a bowl, combine chopped mushrooms, half the spinach, stuffing mix, 2 tablespoons cheese, butter and onion; mix well. Spread over tenderloin. Roll up, starting with a long edge. Secure with toothpicks.
3. Place, seam side down, in a greased 13x9-in. baking pan; brush lightly with browning sauce if desired. Top with remaining spinach; sprinkle with nutmeg. Arrange mushroom caps around meat; sprinkle with remaining Parmesan.
4. Cover and bake at 350° for 30 minutes. Uncover and bake 10 minutes longer or until a thermometer inserted into meat layer reads 160°-170°. Cut into 1-in. slices.
