Preheat the oven to 425 degrees F. Line a baking sheet with a silicone mat or parchment paper.
In a large mixing bowl, combine all ingredients listed before tortillas. Mix thoroughly until well combined.
Warm the tortillas in the microwave to soften, about 20-30 seconds. Place a tortilla on a work surface. Spoon 2-3 tablespoons of the filling mixture down the middle of the tortilla. Roll the tortilla up tightly around the filling. Place seam-side down on a baking sheet. Repeat with the remaining tortillas and filling, spacing the assembled taquitos evenly on the baking sheet. Spray the tops lightly with cooking spray.
Bake 15-20 minutes, until crisp and golden brown. Serve with sour cream and additional salsa, if desired.
