Preheat the oven to 400°. In a large oven-safe skillet, combine the olive oil, chicken, 1-2 tablespoons fajita seasoning, salt, and pepper. Toss to coat. Set the skillet over high heat. Cook until seared all over, minutes. Add the onion and peppers. Season with salt and pepper. Cook until fragrant, about 5 minutes. Remove from the heat and stir in the salsa verde or enchilada sauce. In a bowl, combine the corn, cream cheese, yogurt, chili powder, chives, and salt. Stir in half the cheese. Spoon the corn down the center of each tortilla, tuck, and roll. Place the tortillas seam side down over the chicken. Top with the remaining cheese. Bake for 15-20 minutes, until the cheese has melted. Serve warm, drizzled with mayo, then sprinkle with Tajin or cayenne. Top with avocado, cilantro, and cotija cheese. Enjoy!
