Preheat oven to 400 degrees
Bake the potato for 45 minutes, or until fork tender.
Place the sausage slices in a small frying pan and brown until cooked through. Drain on paper towels.
Wipe the frying pan clean of sausage drippings. Heat the olive oil over medium-low heat until it shimmers, about 1 minute.
While the olive oil is heating, add the chili powder, salt and pepper to the eggs.
Pour the eggs into the pan, and cook to desired scrambled egg consistency.
Halve the cooked sweet potato, and scoop out most of the flesh.
Divide the cooked egg mixture, cooked sausage, and cheese between the sweet potato halves.
Bake until the cheese is melted.
Top with chopped scallions.
