Heat the avocado oil in a large cast iron skillet. Add the onion and saute, stirring occasionally, until onion begins to sweat, about 3 minutes. Add the sweet potato, cover, and cook for 5 minutes.
Remove cover, scoot potatoes to the side, add meat and seasoning. Brown on each side 2 minutes. Stir to mix sweet potato and turkey together. Add broth. Cover and cook 5 minutes.
Remove cover, cook 2 minutes.
Add chopped tomatoes and chives and cook just until everything is warm. Serve and enjoy!
