Flax Seed for Smoothies

Always searching for ways to easily fit more good stuff into smoothies, I came across this product at Trader Joe's.  I put a few teaspoons into the blender along with greek yogurt and frozen berries, and it's not detected at all.  They somehow roasted the flax seed with dried blueberries, so the taste is very mild.  Great for breakfast, or a mid-afternoon snack/pick-me-up!
