Preheat oven to 425F and line a sheet pan with parchment paper.
Toss cubed sweet potatoes with avocado oil, salt, pepper, cinnamon, paprika, garlic powder, and parsley.
Spread sweet potatoes in a single layer on the baking sheet and roast for 25-30 minutes until tender and crispy.
While sweet potatoes roast, brown ground beef in a large skillet over medium heat for 8-10 minutes, breaking it up as it cooks.
Add taco seasoning to the beef and stir in water to deglaze the pan.
Stir in tomato paste if using.
Divide roasted sweet potatoes and beef among bowls.
Add cottage cheese and sliced avocado to each bowl.
Drizzle generously with hot honey and season with salt and pepper to taste.
