Who knew

Salvia hispanica - Wikipedia, the free encyclopedia - also known as "chia seed"... which you can buy at Sprouts!

I didn't find any recipes for chia seeds at the Sprouts site, but this site has some: Purcell Mountain Farms

More info also at Annie Appleseed Project.

Bulk chia seed can be purchased from the following:
Chia Seed and Oil / Arizona Chia
Vinetree Orchards
Herbal Hut
...and many others that will appear for a Google search.
