On a lined baking sheet, spread the diced sweet potatoes. Drizzle with olive oil and sprinkle with cumin, smoked paprika, chili powder, salt, and pepper. Toss until sweet potatoes are evenly coated.
Roast the sweet potatoes in the oven for about 25-30 minutes, or until tender and slightly caramelized, stirring halfway through.
While the sweet potatoes are roasting, heat a small pot over medium heat. Add the black beans and simmer for about 5 minutes until heated through. Add salt and pepper to taste.
Once the sweet potatoes are done, remove them from the oven.
To assemble the tacos, warm the corn tortillas in a dry skillet for 30 seconds on each side.
Load each tortilla with a generous amount of roasted sweet potatoes, a spoonful of black beans, diced red onion, and sliced avocado.
Garnish with chopped cilantro and serve with lime wedges on the side for squeezing over tacos.
