Preheat grill to 350F and cook potatoes wrapped in aluminum foil until tender. It should take about 1 hour 30 minutes.
Raise your grill temperature to 450F.
Let potatoes cool down a little.
Meanwhile, shape the ground beef into burgers patties. Season with salt and pepper and grill well. About 7-10 minutes per side.
Carefully cut lengthwise and scoop out potatoes, leaving a minimum of 1/4" on all sides.
Brush with olive oil then add salt & pepper.
Place potato skins facedown and grill until golden. About 5 minutes.
Flip and fill potato skins with bacon, green onions and cheese. Flip the burger patties as well.
Once ready and cheese is melty, fill the potato skins with your favourite sauce, then top one with a cooked burger and another potato skin.
Enjoy!
