1.Preheat the oven to 400°F (200°C). Toss the cubed sweet potato with a light drizzle of olive oil and a pinch of salt. Spread on a baking sheet and roast for 20–25 minutes, or until tender and lightly browned.
2. While the sweet potato cooks, form the ground beef into patties and season with salt, onion powder, black pepper, and half of the garlic powder. Heat a skillet over medium heat and cook for 4–5 minutes per side, or until fully cooked through.
3. In a medium bowl, combine the shredded cabbage, carrots, olive oil, apple cider vinegar, a dash of salt (to taste), and the remaining garlic powder. Toss until evenly coated.
4. Top the cooked burger with avocado oil mayo and sliced avocado. Serve alongside the fresh slaw and roasted sweet potato.
