Cheesy Onions & Potatoes in foil on Grill

sounds very similar to my cheesy onion and potatoes, except instead of Parmesan, I add cheddar (or the pre-grated Mexican mix cheese or any soft cheese for that matter); instead of mayo I use butter (cubed) and cube the potatoes.

add potatoes, onion and garlic, sprinkle with seasonings, dot with butter cubes. Bake. Once potatoes are cooked, top with cheese and bake a few minutes more until the cheese is melted.
