Why This Method Works
If you tried dinners cooked in foil packs, you know the convenience and ease of no-clean up with this method. I am currently obsessed with these Cheesy Potatoes in Foil Packs that can be baked in the oven or on the grill. In just 20 minutes, the potatoes are cooked perfectly and ready to be topped with cheese to melt into ooey gooey goodness.
The addition of just a tablespoon of onion to each serving gives them even more flavor. If desired, you can top the potatoes with chopped parsley or green onions or a blend of herbs. Want to make a whole meal? Add chicken or sausage and you have dinner ready!

What do you consider medium heat? I am cooking these on my gas grill with a temp gauge on the lid. Would it be 250 or 300?
