4 to 5 large potatoes, sliced thin
1 onion, sliced thin
4 tablespoons butter, melted
2 to 3 teaspoons seasoning salt
1 teaspoon black pepper
1/4 cup grated parmesan cheese
2 cups shredded cheddar cheese, shredded
1/2 pound bacon, cooked and crumbled
A few sheets of heavy-duty foil
Toss the potatoes and onions together with butter, seasoning salt and pepper. Divide the sliced potatoes and onions equally between a few large pieces of heavy-duty foil that have been sprayed with cooking spray. Sprinkle cheddar then Parmesan cheese over the top on potatoes. Then top with bacon.
Bring opposite ends of the foil together and seal to form a packet. Place on grill over medium heat for about 25 to 40 minutes or until potatoes are fork-tender. Remove from grill, carefully open the packets.
You can also bake foil packets on a large baking sheet in a preheated 350 degree oven for 25 to 40 minutes.
