This 9inch diameter, veggie-packed quiche is usually made with three or four different vegetables: a green leaf, such as kale or chard, onion, and sweet pepper, with often additionally mushroom, tomato, and/or a green chile.  You will taste the scrumptious layer of goat chèvre on top!
-- The pie crust is store-bought; see picture. Happy to bake a quiche on a gluten-free pie crust by request.
