Instructions:
Roast Sweet Potatoes: Preheat oven to 400°F (200°C). Toss cubed sweet potato with olive oil, cumin, chili powder, and salt. Spread on a baking sheet and roast for 20-25 minutes, until tender.
Make Crema: While the potatoes roast, combine avocado, lime juice, yogurt, garlic, and salt in a blender. Blend until smooth.
Assemble Tacos: Warm the tortillas. Fill each with roasted sweet potatoes, black beans, and shredded cabbage.
Serve: Generously drizzle with the avocado crema and enjoy immediately.
