Prepare the Filling: In a mixing bowl, combine shredded chicken, Monterey Jack cheese, green onions, cilantro, ground cumin, chili powder, garlic powder, salt, and pepper. Mix well.
Fill the Tortillas: Spoon a generous amount of the chicken mixture onto each tortilla, spreading it along the center.
Roll the Flautas: Roll each tortilla tightly around the filling, creating a cigar-like shape.
Secure with Toothpicks: Use toothpicks to secure the seams of the flautas, preventing them from unraveling during cooking.
Fry the Flautas: In a skillet, heat cooking oil over medium-high heat. Carefully place the flautas seam side down and fry until golden brown and crispy. Use tongs to turn them for even cooking.
Drain and Serve: Place the cooked flautas on a paper towel-lined baking sheet to drain excess oil. Remove toothpicks before serving.
