01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss sweet potato cubes, red onion, and garlic with olive oil, cumin, smoked paprika, chili powder, coriander, salt, and pepper until evenly coated.
03 - Spread the vegetables in a single layer on the prepared baking sheet. Roast for 25-30 minutes, stirring halfway through, until sweet potatoes are tender and slightly caramelized.
04 - While vegetables roast, warm the black beans in a saucepan over medium heat until heated through.
05 - Once roasted, transfer vegetables to a large bowl. Add black beans and chopped cilantro. Toss gently to combine.
06 - Warm tortillas in a dry skillet or microwave until pliable.
07 - Spoon a generous portion of the sweet potato-bean mixture onto the center of each tortilla. Top with cheese, salsa, and a dollop of sour cream or Greek yogurt. Squeeze fresh lime juice over the filling.
08 - Fold the sides of the tortilla over the filling, then roll up tightly from the bottom to form a burrito. Serve immediately, garnished with extra cilantro and lime wedges if desired.
