Making Garlic Steak and Potato Foil Packs is straightforward. Follow these simple steps:

1. Prepare the Foil: Preheat your grill or oven to 400°F (200°C). Cut four large pieces of aluminum foil, about 12 inches each.
2. Combine Ingredients: In a large bowl, mix together the steak pieces, diced potatoes, half of the butter, minced garlic, Italian seasoning, salt, and pepper. Ensure everything is well combined.
3. Create Foil Packs: Place a generous portion of the steak and potato mixture into the center of each foil piece. Top with the remaining butter, cut into small pieces.
4. Seal the Packs: Fold the foil over the mixture, sealing it tightly at the top and sides, creating a secure packet.
5. Cook: Place the foil packs on the grill or in the oven. Cook for 25-30 minutes, or until the steak is cooked to your desired doneness, and the potatoes are tender.
6. Check for Doneness: Carefully open one packet to check if the potatoes are fork-tender. If not, seal it back and continue cooking for a few more minutes.
7. Serve: Once done, remove the foil packs from the heat. Open with caution to avoid steam. Garnish with chopped parsley before serving.
