Cut a wedge, or several large leaves of lettuce into fairly thin strips.  (So it looks shredded.)  To that add some finely chopped green onion and a small, finely grated carrot.  Season with pepper/salt or whatever spices you like, and add 1 T. fat-free Miracle Whip.  Mix well.

A cereal/soup bowl has about 20-30 calories, including the Miracle Whip!  Tasty and filling.
