Follow these simple steps to create your own delicious Ham and Swiss Quiche:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C). This ensures that your quiche will cook evenly and have a perfectly golden crust.
2. Prepare the Pie Crust: Place the pie crust in a pie dish, pressing it gently to fit the shape of the dish. Crimp the edges of the crust to create a decorative border.
3. Mix the Egg Mixture: In a medium-sized bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until fully combined. This mixture will serve as the base for your quiche, binding all the ingredients together.
4. Assemble the Quiche: Evenly spread the diced cooked turkey and shredded Swiss cheese across the bottom of the pie crust. This ensures that every bite is filled with these delicious ingredients.
5. Add the Egg Mixture: Carefully pour the egg mixture over the turkey and cheese in the pie crust. Use a spatula to gently mix the ingredients, ensuring the egg mixture is evenly distributed.
6. Bake the Quiche: Place the quiche in the preheated oven and bake for 35-40 minutes, or until the center is set and the top is lightly golden. You can test for doneness by inserting a knife into the center; if it comes out clean, your quiche is ready.
7. Cool and Serve: Allow the quiche to cool for a few minutes before slicing. This makes it easier to serve and helps the flavors to meld. Slice the quiche into wedges, garnish with fresh herbs if desired, and enjoy!
