Remove from the oven and test for doneness (a fork should easily penetrate the cooked potato without much resistance).
Slice the potato longwise down the middle. Go through the inside of the potato but do not pierce the bottom potato skin. Using a pair of kitchen mitts, press the ends of the potato together, which will crush the inside of the potato and force it open.
Add salt and pepper to taste. Stuff with bacon, cheese, optional jalapeños, and sour cream. Transfer to a dish and microwave on high for 1 ½ minutes to melt the cheese. Add chopped chives or green onions, and serve.
