1/2 cup non-fat vanilla yogurt
1/2 frozen banana
1/2 cup blueberries
1/2 cup skim milk
1/4 cup oatmeal (Old-fashioned oats)

Blend all ingredients until smooth. Delicious but not too sweet. Just right to share with a friend.

Optional: Before serving, plop a small scoop of sugar-free, reduced-fat vanilla ice cream on top.
