Preheat the oven to 400 F
Brush the potatoes with. good coating of canola oil. Sprinkle them with salt and bake them for 35 to 45 minutes, until the ptatoes are tender and the skin is starting to crisp.
Slice the potatoes in half lengthwise. Then use a spoon to cut a rim around the edge of each half and scoop out the insides.
Raise the oven temperature to 425 F.
Brush the skins on the inside with the melted butter, then put them back in the oven for 3 minutes. After that, use tongs to turn the skins to the other side. Brush that side with more butter and return the skins to the oven until crisp, 3 to 4 minutes.
Remove them from the oven. Fill the skins with a small amount of grated Cheddar and place them into the oven long enough to melt the butter.
Sprinkle on some of the bacon, some of the green onions and a dollop of sour cream.
