Peel the sweet potato and dice it into uniform 1/2-inch cubes.
Heat the avocado oil in a large non-stick skillet over medium heat.
Add the sweet potato cubes to the skillet, cover with a lid, and cook for 8-10 minutes, stirring occasionally, until tender and lightly browned.
Remove the lid, increase the heat to medium-high, and add the ground turkey and diced red onion to the skillet.
Break up the turkey with a wooden spoon or spatula and cook until the meat is browned and cooked through, approximately 5-7 minutes.
Stir in the diced red bell pepper, sea salt, black pepper, smoked paprika, and garlic powder.
Sauté for an additional 3-4 minutes until the bell peppers are tender-crisp and the spices are fragrant.
Remove from heat and serve immediately, garnishing with fresh herbs if desired.
