That sounds so good! I don't know why I never thought about adding onions and garlic in with the potatoes in the foil before!Thanks for the idea!We do basically the same, slice them up, put them in foil with some butter, chopped onions, garlic, and salt and pepper. The family loves them and it's easy.
I do something very similar at times, but instead of the sugar I use maple syrup.I sometimes make a prepack before we even leave to have that first night out, something that can chill in the cooler on the drive up to our grounds.
