Preheat oven to 400°F
Lay out a sheet of aluminum foil, long enough to run the length of a sheet pan. Fold foil into a boat shape.
Add half the lobster, shrimp, clams, corn and potatoes.
Season with salt and pepper and drizzle with juice of ½ a lemon and ½ pouch of chimichurri.
Add ½ cup stock to the foil boat. Top with another sheet of foil and fold edges over to completely seal the packet. Add the packet to a sheet pan. Repeat with a second sheet of foil and sheet pan.
Add both sheet pans to oven and bake for 15-20 minutes, until seafood is cooked through and potatoes are soft.
Serve with additional lemon wedges.
