Peel and dice the sweet potatoes into small cubes.

Dice the onion and bell pepper, and mince the garlic.

In a large skillet, heat olive oil over medium heat.

Add the diced onion and bell pepper, sauté for 3-4 minutes until softened.

Stir in the minced garlic and cook for an additional minute.

Add the ground beef to the skillet, breaking it apart with a spatula. Cook until browned, about 5-7 minutes.

Stir in the diced sweet potatoes, cumin, paprika, salt, and black pepper.

Cover the skillet and cook for 15-20 minutes, stirring occasionally, until the sweet potatoes are tender.

Taste and adjust seasoning if necessary before serving.
