Preheat the grill to medium-high heat.

In a mixing bowl, combine ground beef, diced potatoes, mixed vegetables, ranch seasoning, olive oil, salt, and pepper.

Mix well until all ingredients are evenly coated with seasoning.

Cut four large pieces of aluminum foil, about 12 inches long.

Divide the mixture evenly among the foil pieces, placing it in the center of each.

Fold the sides of the foil over the mixture and seal tightly to create packets.

Place the foil packets on the grill and cook for about 30 minutes, turning halfway through.

Remove from the grill and let cool for a few minutes before carefully opening the packets.
