With a small knife cut off the top 1/4 of each potato, discarding the top. Then using a small spoon (I used my 1/4 teaspoon measuring spoon) scoop out the inside of the potato, making sure to the keep skin intact, placing potato flesh into a small bowl. Using a fork or a masher, combine the potato with the bacon, sour cream, green onions & cheese. Once combined, place the mashed potato mixture into a Ziplock bag and cut off the tip of the bag. Pipe the potato mixture into the potato skins, making sure mixture is slightly mounded at the top. Place potatoes back on the baking dish.
