Instructions

  1. Cut potatoes into 1/2-in. cubes; place in a large bowl. Add onions and oil; toss to coat. Spoon into the center of a large piece of heavy-duty foil (about 18 inches x 12 in.) that has been sprayed with pam or use non-stick foil.
  2. Combine the Parmesan cheese, oregano, garlic salt and pepper; sprinkle over potato mixture. Fold foil into a pouch and seal tightly.
  3. Grill, uncovered, over medium-hot heat for 20-30 minutes or until potatoes are tender. Open foil carefully to allow steam to escape.
