These portobello mushroom enchiladas are a flavorful and meaty vegetarian option. The filling is made with sautéed portobello mushrooms, onions, and garlic, seasoned with herbs and spices. The enchiladas are then rolled up in flour tortillas, topped with a smoky chipotle enchilada sauce, and baked until the cheese is melted and bubbly. Serve them with a side of Mexican street corn and a sprinkle of fresh cilantro for a burst of flavor.
