01 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spatula, until browned and cooked through, about 5-6 minutes. Drain excess fat if necessary and transfer beef to a plate.
02 - Add the remaining 1 tablespoon olive oil to the same skillet. Add the diced sweet potatoes and cook for 4-5 minutes, stirring occasionally.
03 - Add the diced onion and red bell pepper. Continue to cook for 4-5 minutes, until vegetables begin to soften.
04 - Return the cooked ground beef to the skillet. Add chili powder, cumin, smoked paprika, salt, and black pepper. Stir well to combine.
05 - Reduce heat to medium-low, cover, and cook for 8-10 minutes, stirring occasionally, until sweet potatoes are tender.
06 - Uncover and cook another 2-3 minutes to allow any excess moisture to evaporate.
07 - Serve hot, garnished with cilantro, avocado, and shredded cheese as desired.
