Wild Spinach Quiche With Mushroom And Cheddar
This simple Wild Spinach Quiche with mushrooms and cheddar cheese is a tasty and easy bake. The mild, slightly earthy flavor of wild spinach pairs perfectly with the richness of the mushroom and sharp cheddar, all in a simple crust. Wild spinach (Chenopodium album) grows in abundance in our rather wild little garden, and this year, and has replaced the spinach that I had intended to grow (but forgot to water).

Wild Spinach
It’s often dismissed as a weed, but it’s a nutritional powerhouse, and compared to other wild plants, its flavor is surprisingly mild. Depending on its location, it has a range of names, including lamb’s quarters, fat hen, pigweed, Goosefoot, and, rather simply, Indian Spinach.
As always, bring a reliable guidebook and double-check before foraging.
