Scrub the potatoes under cold water, then dry them thoroughly. Pierce each potato several times with a fork and rub them with olive oil, salt, and pepper.
Bake the potatoes directly on the oven rack for about 45-60 minutes, or until they are tender and the skins are crispy.
While the potatoes are baking, heat a skillet over medium heat. Add ground turkey or beef and cook until browned, breaking it apart with a spatula.
Stir in taco seasoning and follow package instructions, adding a little water if necessary. Cook for another 5 minutes, then set aside.
Once the potatoes are done, let them cool slightly. Cut each potato in half lengthwise and scoop out a bit of the flesh, leaving a thin layer on the skin.
Brush the insides of the potato skins with olive oil and place them cut side down on a baking sheet. Return them to the oven and bake for an additional 10-15 minutes until they are crispy.
Remove the potato skins from the oven and flip them over. Spoon the cooked taco meat into each skin generously.
Top with black beans, diced tomatoes, and sprinkle cheddar cheese over each skin.
Return to the oven for another 5-10 minutes, or until the cheese is melted and bubbly.
Once out of the oven, drizzle sour cream and top with jalapeños and green onions.
