Dice the potatoes and carrots into 1/2-inch pieces. Chop the onion. Slice the beef smoked sausage into 1/2-inch rounds.

In a large bowl, toss the beef sausage, potatoes, carrots, and onions with olive oil, garlic powder, salt, and black pepper.

Cut four 12x12 inch sheets of heavy-duty aluminum foil. Divide the mixture evenly among the center of each foil sheet.

Fold the sides of the foil over the food, sealing the edges tightly to create a packet. Store in a sealed container or ziplock bag in your cooler until ready to cook.

To cook, place the foil packets on hot campfire coals or a grill for 25 to 30 minutes, turning once halfway through, until vegetables are tender.
