shrimp, corn, potatoes, and smoked sausage with flavorful seasonings

Instructions:
Preheat the Grill:
Preheat your grill to 400˚F (204˚C). Prepare 4 large foil sheets, each measuring about 12×12 inches.
Boil Potatoes and Corn:
Add 8 cups of water to a large pot and bring to a boil over high heat. Add the potatoes and corn to the boiling water. Reduce the heat to maintain a steady simmer and continue to cook for 10 minutes. Drain the vegetables.
Combine Ingredients:
In a large mixing bowl, combine the boiled potatoes and corn with the raw shrimp, sausage, sliced onion, and minced garlic.
Season:
Pour the melted butter over the shrimp mixture. Add salt, pepper, and Old Bay seasoning. Stir everything together until well mixed.
Prepare Foil Packets:
Divide the shrimp mixture evenly among the four foil sheets. Wrap the foil around the ingredients, sealing the edges tightly to form packets.
Grill:
Place the foil packets directly on the grill. Cook for about 15 minutes, flipping once halfway through to ensure even cooking.
Serve:
Carefully open the foil packets (watch out for steam). Garnish with slices of lemon and chopped parsley before serving.
