Preheat oven to 400°F (204°C). Toss sweet potatoes with 1 tbsp olive oil, paprika, garlic powder, cinnamon, salt, and pepper. Spread on a baking sheet and roast for 40–45 minutes, flipping halfway.
Heat the remaining olive oil in a skillet over medium heat. Add onions and cook until soft and translucent.
Add ground beef to the pan. Break it apart as it browns, then stir in taco seasoning. Cook until beef is fully browned and coated.
Assemble the bowl: Start with roasted sweet potatoes, add the beef, avocado slices, and cottage cheese or Greek yogurt.
Drizzle hot honey over the top just before serving. Garnish with cilantro, red pepper flakes, or lime juice if desired.
