Creating Taco Potatoes is as simple as following these steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).

2. Prepare the Potatoes: Wash the potatoes thoroughly and prick them with a fork several times. Rub with olive oil and sprinkle with salt.

3. Bake the Potatoes: Place the potatoes directly on the oven rack or on a baking sheet. Bake for 45 minutes or until the skins are crispy and the insides are tender.

4. Cook the Protein: While the potatoes bake, heat a skillet over medium heat. Add the ground beef or turkey, breaking it apart with a spoon. Cook until browned.

5. Season the Meat: Drain excess fat if needed. Stir in the taco seasoning and a splash of water. Cook for an additional 5-7 minutes, mixing until well combined. Set aside.

6. Heat Black Beans and Corn: In another saucepan, combine the rinsed black beans and corn. Heat over medium until warmed through. Set aside.

7. Assemble the Taco Potatoes: Once the potatoes are done baking, remove them from the oven. Let them cool for a few minutes before slicing them in half lengthwise.

8. Fluff the Potatoes: Use a fork to fluff the insides. Season with salt and pepper to taste.

9. Add Toppings: Layer the taco meat, black beans, corn, and shredded cheese on top of the fluffed potato. You can return them to the oven for an additional 5 minutes to melt the cheese.

10. Garnish: Remove from the oven; top with sour cream, diced tomatoes, avocado, green onions, and cilantro if desired.

11. Serve Immediately: Plate the Taco Potatoes and watch your guests enjoy!
