You'll have this dish on the table in under 15 minutes. (No, we're not kidding.) Serving it with lots of crusty bread is a must: You'll want to sop up every last drop of broth. We love the hint of anise from the tarragon.
After you've had your first serving, refrigerate the remainder in the blender jar, and when you're ready for more, simply re-pulse. (Alternatively, you can freeze the extra smoothie in popsicle molds for a breakfast pop.)
