Preheat oven to 425°F and line a baking sheet with parchment paper.
Slice the sweet potato into thin, uniform wedges or fries.
Toss the sweet potato wedges with olive oil, sea salt, and black pepper until evenly coated.
Spread the fries in a single layer and roast for 20-25 minutes, flipping halfway through until golden and crispy.
While the fries roast, brown the ground beef in a large skillet over medium-high heat.
Add the diced red onion and bell pepper to the skillet, sautéing until the vegetables are tender.
Stir in the garlic powder and chili powder, cooking for another minute until fragrant.
Arrange the roasted sweet potato fries on a plate and pile the beef and vegetable mixture on top.
Garnish with fresh salsa, avocado slices, and chopped cilantro before serving.
