Wash and scrub the potatoes thoroughly, then prick them with a fork.
Place the potatoes on a baking sheet and brush them with olive oil.
Season with salt and bake for 45 minutes, or until fork-tender.
Once baked, remove the potatoes and let them cool slightly, then halve them.
Scoop out some flesh from each half, leaving a thin layer.
Brush the insides with olive oil, season, and return to the oven for 10 minutes.
Remove from the oven and fill each skin with a sprinkle of cheese and crumbled bacon.
Return to the oven and bake for another 10 minutes, or until the cheese is melted and bubbly.
