Thoroughly wash and scrub the potatoes, then pat them dry. Prick each potato several times with a fork.
Rub each potato with olive oil and sprinkle with salt. Bake for 45-60 minutes until tender.
Let the potatoes cool for 5-10 minutes, then slice each in half lengthwise and scoop out the flesh.
In a mixing bowl, combine the scooped potato flesh with cheddar cheese, Monterey Jack cheese, black beans, corn, diced tomatoes, sliced jalapeños, and taco seasoning. Mix well.
Spoon the filling back into each potato skin half, ensuring they are well filled.
Place the stuffed potato skins on a baking sheet and bake for an additional 15-20 minutes until the cheese is melted and bubbly.
Remove from the oven, let cool slightly, and top with sour cream, guacamole, and fresh cilantro.
Notes
Serve on a vibrant platter with extra cilantro and jalapeño slices for garnish.
