A passage from Wild Edible Plants of New Mexico:

Simply a pleasant tasting (slightly cucumber–like) potherb, eat Chickweed fresh or as a boiled/steamed green. The leaves and flowers are more palatable than the stems. Many species are a bit hairy. They quickly become tiresome if consumed in large (more
than a handful) quantities.
