Sweet Potato, Corn, and Black Bean Enchiladas (vegetarian)

"These enchiladas are pure (healthier) comfort food. Warm sweet potatoes, slightly spicy corn and beans, all smothered in cheese and red sauce. They’re satisfying, hearty, and you’ll never miss the meat. They're vegetarian and to keep vegan, just swap the cheese for vegan cheese. The sweet potatoes add bulk, body, and provide a meat-like heft to the enchiladas, minus the meat. I used Trader Joe’s Cowboy Caviar, but most any chunky, corn-heavy or bean-heavy salsa will work, or use cooked and seasoned corn and beans. There’s so much texture in every bite. Juicy corn, firm black beans, gooey cheese, drippy sauce, and chewy enchilada shells. It’s a comfort food party in your mouth with every bite. The recipe is easily doubled for larger families, planned leftovers, or parties...."
