Roast the Sweet Potatoes:

1. Preheat your oven or air fryer to 425°F (218°C).
2. In a large bowl, combine 1/2 tablespoon avocado oil, juice from half the lime, 1/2 teaspoon salt, and 1/2 teaspoon black pepper.
3. Add the diced sweet potatoes to the bowl and toss to coat evenly.
4. Spread the sweet potatoes on a lined baking sheet (if using the oven) or place them in the air fryer basket.
5. Roast for 20-25 minutes until tender and slightly browned.

Cook the Turkey Mixture:

1. While the sweet potatoes are roasting, heat the remaining 1/2 tablespoon avocado oil in a large skillet over medium heat.
2. Add the chopped onion and cook for about 3 minutes until translucent.
3. Add the ground turkey to the skillet and cook until no longer pink.
4. Stir in the minced garlic, chili powder, cumin, smoked paprika, oregano, remaining salt, and black pepper. Cook for an additional 2 minutes to allow the spices to meld.
5. Mix in the black beans and cook until heated through.

Combine and Serve:

1. Once the sweet potatoes are done roasting, add them to the skillet with the turkey mixture. Stir to combine all ingredients thoroughly.
2. Squeeze the remaining half of the lime over the skillet and stir.
3. Garnish with chopped cilantro if desired and serve warm.
