Preheat oven to 350°F.
Rinse and clean your potatoes, then bake for 60 minutes. (Cooking tip: To reduce cook time, microwave potatoes for about 12 minutes.)
Once potatoes are done and tender, slice them in half lengthwise.
Using a spoon, begin scooping out the insides of the potatoes until there is just a thin layer of the insides left.
Cook the ground beef. Sprinkle your taco seasoning into the beef and mix well.
Turn off heat and divide the beef mixture into the hollowed potato skins.
Sprinkle with the shredded cheese and bake until cheese is melted.
Place your skins on your serving tray and top with shredded lettuce or red cabbage, diced tomato and chiles, jalapeno (optional), and a dollop of sour cream. Top with cilantro.
