Place the wings in a large bowl and sprinkle all over with sea salt and pepper. In a large measuring cup, whisk together the oil, lemon juice, zest, garlic, salt and pepper.
Pour about 3/4 of this mixture over the wings and toss to coat. Save the remaining marinade for after grilling. Cover the bowl with plastic wrap and marinate for 1–2 hours.
Divide the wings between two 16-inch sheets of Reynolds Wrap® Heavy Duty Foil to create foil packets. Discarding excess marinade, place with wings in the center of each foil sheet. Wrap and seal the foil packets tightly on the long and short ends.
Heat your grill to high heat, place both foil packets on the grill, and grill for a total of 20–25 minutes, turning once midway. Before serving, stir the parsley into the remaining lemon-garlic mixture and drizzle over the wings to serve. Enjoy!
