Preheat the Oven: Start by preheating your oven to 375°F (190°C). This is where the magic happens!
Prepare the Tortillas: Using cooking spray or a bit of oil, lightly grease a round 9-inch pie dish. Place your tortillas in the dish, overlapping them slightly to cover the bottom and sides completely.
Whisk the Eggs: In a large mixing bowl, crack the six eggs, and add the milk. Whisk them together until well combined. Don’t be shy; you want the mixture to be fluffy!
Add Vegetables and Cheese: Fold in the diced vegetables and shredded cheese into your egg mixture, seasoning with salt and pepper. Ensure everything is evenly distributed.
Pour the Filling: Carefully pour the egg and vegetable mixture into the tortilla-lined pie dish. Make sure it’s evenly spread.
Bake: Place it in the preheated oven and bake for about 25-30 minutes, or until the egg is set and the top is slightly golden.
Cool and Slice: Once baked, allow the quiche to cool for a few minutes before slicing it into wedges. This let’s the flavors set and makes serving easier.
Enjoy!: Serve your high protein quiche warm, topped with your choice of salsa or avocado for an added flavor burst.
