This ratatouille quiche is a delightful dish that combines the flavors of ratatouille with a creamy egg custard. Using a food processor, you can quickly chop the vegetables and mix them with eggs, cream, and cheese to create a flavorful filling. Pour the mixture into a pre-baked pie crust and bake until the quiche is set and golden brown. It's a perfect dish for brunch or a light lunch.
