How to Make It
Heat oven to 400° F. Place the chicken on a rimmed baking sheet. Rub with the oil and season with ½ teaspoon salt and ¼ teaspoon pepper. Roast, until cooked through, 14 to 16 minutes; let cool, then shred.
In a medium bowl, toss the chicken with 1 cup of the Cheddar. Dividing evenly, roll up the chicken mixture in the tortillas and place seam-side down in an 8-inch square baking dish. Top with the enchilada sauce and the remaining ½ cup of Cheddar. Bake until heated through, 15 to 20 minutes. Sprinkle with the cilantro.
