Follow these simple steps to create Easy Breakfast Quiche:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare the Crust: Place the pre-made pie crust into a 9-inch pie dish. Press it gently into the sides and trim excess dough if necessary.
3. Whisk Eggs: In a large bowl, crack the six eggs and whisk until fully beaten. You can add a pinch of salt and pepper at this stage for extra flavor.
4. Add Ingredients: Stir in the shredded cheese, diced vegetables, and cooked meat into the egg mixture. Combine evenly.
5. Pour Filling: Carefully pour the egg and filling mixture into the prepared pie crust, ensuring it is evenly distributed.
6. Bake: Place the quiche in the preheated oven and bake for 30-35 minutes, or until the edges are golden and the center is set.
7. Cool: Once finished baking, remove the quiche from the oven and allow it to cool for 5-10 minutes. This resting period helps it set further for easier slicing.
8. Slice and Serve: Cut into wedges and serve warm, or refrigerate to enjoy later.

With these simple steps, preparing Easy Breakfast Quiche becomes an effortless task.
