Preheat the oven to 425 degrees F.
In a large bowl, add the diced sweet potatoes, olive oil, cumin, chili powder, garlic powder, paprika, and salt. Toss well to combine.
Spread the sweet potatoes out on a greased baking sheet. Bake in the preheated oven for 25-30 minutes, stirring the sweet potatoes halfway through.
Meanwhile, heat a medium skillet over medium-high heat.
Add the ground beef and cook until browned, breaking it up into small pieces as it cooks.
Once browned, add the taco seasoning and follow directions on taco seasoning packet. If using homemade, just add ~2 tablespoon of water and cook until combined.
Once sweet potatoes and beef are cooked, assemble the bowls.
To each bowl, add ¼ of the beef, ¼ of the sweet potatoes, ½ cup black beans, ½ of an avocado, and ½ cup of cottage cheese.
Top with pickled onions, pickled jalapeños, a dollop of salsa (if desired), and a sprinkle of chopped cilantro. Serve and enjoy!
