Peel and dice the sweet potato into small half-inch cubes and finely shred the Brussels sprouts.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the diced sweet potatoes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are tender and golden brown.
Push the potatoes to one side of the pan and add the ground chicken, breaking it up with a spatula as it cooks.
Once the chicken is mostly browned, stir in the shredded Brussels sprouts, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Continue to sauté everything together for another 5-7 minutes until the sprouts are softened and the chicken is fully cooked through.
Adjust seasoning to taste and serve immediately while hot.
