Step 1

Heat gas or charcoal grill. Cut 2 (18x12-inch) sheets of heavy-duty foil. Spray with cooking spray.

Step 2

Add cut potatoes to medium bowl. Drizzle with oil; sprinkle with ranch dip mix. Add jalapeño chile; stir until evenly coated. Place equal amount of mixture on center of each sheet of foil. Evenly sprinkle with bacon.

Step 3

Bring up 2 sides of foil so edges meet. Seal edges, making tight 1/2-inch fold; fold again, allowing space for heat circulation and expansion. Fold other sides to seal.

Step 4

Place packs on grill over medium heat. Cover grill; cook 12 minutes. Rotate packs 1/2 turn; cook 12 to 14 minutes longer or until potatoes are tender. Remove packs from grill, cut large X across top of each pack. Carefully fold back foil, and sprinkle potatoes with cheese. If desired, garnish with sliced jalapeño chile.
