Chipotle Cauliflower Tacos with Creamy Jalapeño Verde

Heat the olive oil in a large skillet over high heat. Add the cauliflower, poblano, and onion. Cook, stirring occasionally, until the cauliflower is charring, about 5 minutes. Add the chipotle peppers, enchilada sauce, oregano, salt, and 1/3 cup water. Reduce the heat to medium and simmer until the sauce has thickened slightly, about 10 minutes. Meanwhile, make the Jalapeño Verde. Combine all ingredients in a blender and blend until smooth and creamy. Season with salt.To serve, stuff the avocado, corn, and cauliflower into the warmed tortillas. Top with jalapeño verde sauce and crumbled cheese.
