I saw this on WebMD and immediately got hungry!

Blueberry Smoothie

A fruit smoothie offers a scrumptious way to get in some extra calcium and antioxidants during your day. Try blending 1/3 cup of nonfat yogurt with 2/3 cup of frozen blueberries and ice. “It’s very refreshing and very cold,” Blake says. “That slows down your ability to drink quickly.” Snacks that take more time to finish are often more satisfying.

Although each recipe has varying amounts of saturated fat, they are all under 100 calories. Notice that the portion sizes are small.  And children can prepare most of these snacks themselves with parents operating the blender and supervising portion sizes.
