Heat oven to 350°F. Line cookie sheet with cooking parchment paper or silicone baking mat.
Microwave egg scramble as directed on bag.
Unroll pie crust. Cut 3 (6-inch) rounds from crust. Divide egg scramble mixture equally among crust rounds. Fold crust over on each to make half-circle. Using fork, press edges firmly to seal. Brush tops with beaten egg. Place on cookie sheet.
Bake about 20 minutes or until crust is golden.
