Creating Taco Potatoes is straightforward if you follow these steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Potatoes: Scrub the potatoes and pierce each several times with a fork. Rub them lightly with olive oil and sprinkle with salt.
3. Bake the Potatoes: Place them on a baking sheet and bake for about 45 minutes, or until fork-tender.
4. Cook the Meat: While the potatoes are baking, heat a skillet over medium heat. Add the ground beef and cook until browned. Drain any excess fat.
5. Add Seasoning: Stir in the taco seasoning with about two-thirds of a cup of water and let it simmer for about 5 minutes.
6. Assemble Taco Potatoes: Once the potatoes are cooked, remove them from the oven. Cut a slit down the center of each potato and gently fluff the insides with a fork.
7. Fill with Toppings: Spoon the seasoned meat into each potato, then top with salsa, cheese, green onions, diced tomatoes, and lettuce.
8. Melt the Cheese: Return the stuffed potatoes to the oven for an additional 5-10 minutes until the cheese is melted.
9. Serve with Sour Cream: Garnish with a dollop of sour cream before serving.

Follow these steps, and you will create mouthwatering Taco Potatoes, perfect for any gathering or just a cozy meal at home!
