Chia seeds are a "super food," one of those foods that is ridiculously healthy for you. 1/4 c of these tiny little seeds provides 25% DV calcium, and they are a better source of Omega-3 than salmon. They can be easily added to all sorts of dishes. Since they are so small, you can mix them into things and not even notice them there.
I tried them for the first time tonight, and just mixed them into my salad. It was rather too much chia seed and not enough salad, but I believe I can make them more appealing if I find something else to mix them into, or simply add less seeds to a salad of that size. They absorb 10 times their weight in water, so they get rather gelatinous when you chew them up. It's quite an odd feeling. I think they would be better off getting mixed into yogurt or a smoothie.
I had some delicious pasta and meatballs with my chia salad.
