Preheat your oven to 375°F (190°C).
Roll out the pre-made pie crust and fit it into a 9-inch pie dish.
In a mixing bowl, whisk together the eggs and heavy cream until well combined.
Stir in the shredded cheese and chopped vegetables.
Season the mixture with salt and pepper to taste.
Pour the egg mixture into the crust, spreading it evenly.
Bake in the preheated oven for 35-40 minutes or until the filling is set and lightly golden.
Remove from the oven and let it cool for 10 minutes before slicing.
Garnish with fresh herbs if desired.
Serve warm or at room temperature.
