Step 1

Preheat the grill to 400 degrees. *See notes for campfire and oven directions.* Cut four strips of heavy duty aluminum foil about 2 ft long.

Step 2

Add the beef, salt, pepper, garlic powder, and Worcestershire sauce to a bowl. Use your fingers to gently work the seasonings into the beef. Form into four patties.

Step 3

Combine the potatoes, mushrooms, and onions with the olive oil and garlic powder, paprika, oregano, and parsley. Sprinkle with salt and pepper.

Step 4

If you're making these on the campfire, lay a cabbage leaf on the bottom of each strip of foil before adding the veggies. Otherwise, layer the packets with veggies first and the burger patty on top.

Step 5

Bring the two short sides together and fold them down to seal. Fold/roll up the remaining two sides.

Step 6

Place directly on the grill grates, cover and cook for 25-30 minutes, or until the burger registers 165 degrees.

Step 7

Carefully (really carefully--the steam can be very hot!), unwrap the packets. If desired, place a slice of cheese on top of each burger. Loosely roll back up and allow the cheese to melt for a few minutes. Top the burgers with Miracle Whip or Heinz Simply Ketchup plus your favorite toppings and serve.
