Peel and dice the sweet potato into small, uniform half-inch cubes to ensure even cooking.
Heat the extra virgin olive oil in a large cast-iron skillet over medium heat.
Add the sweet potato cubes to the skillet and sauté for 8-10 minutes, stirring occasionally, until they are tender and develop a golden-brown exterior.
Stir in the diced yellow onion and red bell pepper, cooking for an additional 3-4 minutes until the vegetables have softened.
Push the vegetable mixture to the edges of the pan and place the ground bison in the center.
Brown the bison for 5-6 minutes, breaking it into small crumbles with a spatula, until it is fully cooked through.
Season the entire skillet with smoked paprika, garlic powder, sea salt, and black pepper, tossing well to combine all ingredients.
Remove from the heat and garnish with freshly chopped parsley before serving.
