Using a wooden spoon, place a potato on top of the spoon and cut thin slices leaving the potato attached at the bottom. The spoon should allow you to cut all the way down without cutting through the entire potato! Repeat with all potatoes.
Melt the butter with the garlic powder and paprika. Baste all the potatoes with butter. Then, sprinkle with salt and pepper and wrap each potato tightly in foil.
Heat your grill over low heat. Add the potatoes to the grill and cook for about 20 minutes on each side.
Your potatoes should be slightly soft when you push on the side of the potato. If they still feel very hard, cook for about another 5-10 minutes. All grills are different so rotate the potatoes if you know your grill has hot spots.
Remove potatoes from grill and carefully remove the foil - potatoes will be hot! Sprinkle shredded cheese on top and let the cheese melt onto the potato. Finish with sour cream, chopped bacon and green onions! Enjoy!
