Preheat your oven to 375°F (190°C).
Place the pie crust in a 9-inch pie dish and prick the bottom with a fork.
In a mixing bowl, whisk together the eggs and heavy cream until well combined.
Stir in the shredded cheese, diced vegetables, and cooked meat.
Season the mixture with salt and pepper to taste.
Pour the egg mixture into the prepared pie crust.
Bake in the preheated oven for 35-40 minutes, or until the center is set and the top is golden.
Allow the quiche to cool for 10 minutes before slicing.
Serve warm or at room temperature.
Enjoy your delicious breakfast quiche!
