In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced sweet potatoes and cook for about 10 minutes, stirring occasionally, until they start to soften and begin to brown.
Remove the potatoes from the skillet and set aside.
In the same skillet, add the remaining tablespoon of olive oil. Add the ground beef, breaking it up with a spoon, and cook until browned and fully cooked, about 8-10 minutes. Drain any excess fat if necessary.
Add the diced onion, bell peppers, and minced garlic to the skillet with the ground beef. Cook for another 5 minutes, until the vegetables are tender.
Return the cooked sweet potatoes to the skillet. Add the smoked paprika, ground cumin, salt, and pepper. Stir to combine and cook for an additional 5 minutes, allowing the flavors to meld together.
Garnish with chopped fresh parsley and serve hot.
