I heard of people using potatoes and then topping them with a bunch of taco type stuff. I actually have that planned for this week. I'll let you know how it goes.

Split them open and top with:
black beans or ground beef
red and green bell pepper
Broil them until the cheese melts and the beans are warm.
Then finish with:
You could also put in chicken, broccoli and top with some cheese. Isn't there a place in Atlanta that is famous for their topped baked potatoes? Seems like Williamson Brothers does a version of it too.
You can also make mashed potatoes, adding a sweet potato into the mix. It makes them beautifully orange and yummy delicious!
