01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Toss diced sweet potatoes with 1 tablespoon olive oil, cumin, smoked paprika, chili powder, coriander, salt, and pepper. Spread on prepared baking sheet and roast for 20 minutes, until tender and lightly caramelized.
03 - Heat a large skillet over medium heat, add a splash of oil, and sauté red onion, garlic, and bell pepper for 4 to 5 minutes until softened.
04 - Add roasted sweet potatoes, black beans, corn, jalapeño (if using), lime juice, and cilantro to the skillet. Stir to combine, cook 2 to 3 minutes, and adjust salt and pepper to taste. Remove from heat.
05 - Lower oven temperature to 375°F.
06 - Spread ½ cup enchilada sauce on the bottom of a 9x13-inch baking dish.
07 - Spoon filling evenly onto each tortilla, roll tightly, and place seam-side down in the baking dish. Repeat with all tortillas.
08 - Pour remaining enchilada sauce over rolled tortillas, sprinkle with cheese, cover with foil, and bake for 20 minutes. Remove foil and bake an additional 10 to 12 minutes until cheese is bubbly and golden.
09 - Allow enchiladas to cool for 5 minutes. Garnish with extra cilantro and serve with lime wedges.
