Preheat oven to 450°F.
Wash, scrub, and cut the potatoes in half, lengthwise.
Place the potatoes in a pot and cover them with water. Place the pot over high heat and bring the potatoes to a boil. Reduce the heat to medium and cook the potatoes for 10-12 minutes until they are fork tender but not falling apart.
Drain the potatoes very well and using a spoon, scoop out some of the potato to create little potato boats (the filling can be saved for soups, mashed potatoes, etc).
Arrange the potato boats on a baking sheet lined with foil. Brush the inside of the potato boats with olive oil and season them with salt and pepper.
Place in the oven and allow the potatoes to roast for 10-15 minutes or until they are golden brown. Remove from the oven and keep them warm until ready to use.
Spoon about 2 tablespoons of chili into the potato shells and top each one with a tablespoon of shredded cheddar cheese.
Place the stuffed shells under the broiler for 1-2 minutes or until the cheese is melted.
Remove the tater shells from the oven and garnish with black beans, green onions, and sour cream to make spooky ghosts. Enjoy!
