Make Ahead Prep: The egg mixture can be made a day ahead of time and stored in the fridge until ready to use. You can also prepare the taquitos and instead of baking right away, cover tightly in plastic wrap and store in the fridge overnight, or freeze for later use. To prepare frozen taquitos, place (un-thawed) directly on a baking sheet sprayed with non-stick spray. Follow original baking instructions, increasing time by 5 minutes or until taquitos are golden brown.
