03 - Wrap tortillas in a damp paper towel and microwave for 30–45 seconds until pliable and easy to roll.
04 - Place about 2 tablespoons of the chicken filling along one edge of each tortilla. Roll up tightly and place seam-side down on the prepared baking sheet.
05 - Brush or spray the tops and sides of taquitos lightly with vegetable oil to ensure even browning.
06 - Bake for 18–22 minutes, or until golden brown and crispy, turning once halfway through for even crispiness on all sides.
07 - Serve hot immediately with salsa, guacamole, sour cream, and fresh lime wedges for dipping.
