Served with sour cream.
In a mixing bowl, combine the shredded cooked chicken, cream cheese, sour cream, shredded cheese, taco seasoning, and green onions. Mix until well combined.
Lay a tortilla flat on a clean surface. Place about 2-3 tablespoons of the chicken filling in the center of the tortilla. Fold the sides over the filling and roll it up tightly to form a chimichanga. Repeat with the remaining tortillas and filling.
In a large skillet, heat oil over medium heat. Once hot, place the filled chimichangas seam-side down in the skillet. Cook for about 3-4 minutes on each side, or until golden brown and crispy.
Remove the chimichangas from the skillet and let them drain on paper towels. Serve warm with sour cream on the side.
