Preheat the oven to 375°F.

Place the pre-made pie crust in a 9-inch pie dish and press gently into the bottom and up the sides.

In a skillet, sauté the choice of vegetables until tender.

In a mixing bowl, whisk together the eggs and heavy cream until well blended.

Stir in salt, pepper, garlic powder, and half of the cheese.

Add the sautéed vegetables and optional meat to the egg mixture and stir until evenly coated.

Carefully pour the 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.

Let the quiche rest for 10 minutes before slicing.
