Heat olive oil in a large skillet over medium-high heat until glistening.
Add diced sweet potatoes and cook for about 10-12 minutes, stirring regularly, until they begin to brown and become fork-tender.
Add onion and bell pepper, sautéing until the onion becomes translucent (about 2-3 minutes).
Stir in garlic, cumin, smoked paprika, salt, and pepper.
Add the black beans and cook for another 3-4 minutes until everything is heated through.
