The beauty of this one is it's easy, it's a complete meal, minimal cleanup, it's fun ....oh, yeah....and it's delicious and nutritious. It can easily be made ahead of time -- you could even pop them in the cooler, head up north, throw them on the grill while you set up camp, and once you're done you have a nice hot meal waiting for you.
Start with a piece of tin foil -- about 15"-18" long. I used heavy duty foil to make sure it was sturdy.
Place a hamburg patty in the center.
Add some sliced potatoes -- slice them quite thin so they'll be done at the same time of the other ingredients.
Add some carrot slices -- again sliced thin.
Now some onions.
Lastly, add some cabbage.
Add a second piece of tin foil on top and fold around all edges, forming a good seal. If desired, you get use two pieces on top so you could create a seam down the center (makes it easier to check on cooking progress).
