Preheat your oven or grill to 400°F (200°C).

In a large bowl, combine the ground beef, diced potatoes, sliced carrots, chopped onion, and olive oil. Add garlic powder, onion powder, paprika, salt, and pepper, and mix well.

Cut four pieces of aluminum foil, each measuring approximately 12 inches long. Lay them flat, shiny side up.

Spoon portions of the mixture into the center of each piece of foil. Fold the sides over and roll the ends tightly to seal.

Place the packets on the grill or a baking sheet in the oven. Cook for 30-35 minutes, flipping halfway through if grilling.

Carefully remove the packets from the grill/oven using tongs. Let cool slightly before opening.
