Pre-heat oven to 350.
Line a 9" x 12" baking dish with aluminum foil and coat generously with
nonstick cooking spray.
Whisk together eggs, milk, flour, salt and pepper until smooth (I use an electric
mixer).
Stir in scallions.
Pour mixture onto baking sheet.
Bake until set (do not overbake).
Sprinkle evenly with cheese and bake an additional 2 minutes.
Allow to cool for 5 minutes.
Using a spatula, release the edges from the aluminum foil. Using the spatula and foil,
roll up jellyroll style.
