This is not a frittata. For preparing multiple servings, prep all ingredients and have your mise en place (your prepared ingredients and equipment) at hand to create multiple servings. You can save some time by preparing the filling in a single batch. I also like to add a small splash of vermouth to the filling once the mirepoix has softened, and then let it evaporate during the heating of the turkey. There's plenty of room to have fun with your creativity. Hope you enjoy.
Omelette will continue to cook after heat is turned off; the egg should be set and still soft and slightly creamy inside.
