These Sweet Potato Enchiladas in Creamy Chipotle Sauce are a delicious and satisfying vegetarian dish. The sweet potatoes are roasted until tender and then mashed with black beans, corn, and spices. The mixture is rolled up in tortillas and smothered in a creamy chipotle sauce made with adobo sauce, sour cream, and vegetable broth. The enchiladas are baked until bubbly and golden, and then topped with fresh cilantro and avocado. Serve with a side of Mexican rice and enjoy!
