I just found these at Trader Joes and have to rave about them! I've been trying to get more greens into my diet, they're so good for us but I just can't get past the strong smell and flavor. These plants are a form between "sprout" and "baby" and are known to have an even more concentrated form of the nutritional benefits. They were $1.99 for two 1cup servings, but apparently are very easy to grow yourself, just like sprouts or herbs.
I highly recommend these, they can go in salads or mixed into other recipes very well.
