Lamb's quarters (Chenopodium album), also called fat hen, white goosefoot, wild spinach, Indian bathua and one of the Mexican quelites, is a fast-growing annual leafy green of the amaranth family, foraged and cultivated on every inhabited continent. Its soft, diamond-shaped leaves — dusted with a fine mealy white bloom underneath — cook down like a richer, earthier spinach, and it is one of the most widely eaten wild greens on earth.
