1. Bake Potatoes: Preheat oven to 400°F (200°C). Scrub potatoes, pat dry, pierce with a fork, rub with olive oil, and sprinkle with salt. Bake directly on the oven rack for 50-60 minutes until tender.

2. Make Taco Meat: While potatoes bake, brown the ground beef in a large skillet over medium-high heat. Drain excess grease.

3. Simmer Filling: Return beef to skillet. Stir in taco seasoning and 1/2 cup of water. Simmer for 3-5 minutes until the sauce has thickened.

4. Assemble: Slice baked potatoes open lengthwise. Fluff the insides with a fork. Spoon the taco meat generously into each potato.

5. Melt Cheese: Top each loaded potato with a large handful of shredded cheddar cheese. Return to the oven for 2-5 minutes, or until the cheese is bubbly and melted.

6. Serve: Remove from oven, add your favorite toppings, and serve immediately.
