Dietitian's tip: Orange juice is an excellent source of potassium, a mineral that helps to regulate blood pressure and cell function. If you want to substitute a banana instead of the orange juice, the potassium content is similar.

In a blender, combine the frozen yogurt, milk and orange juice concentrate. Blend until smooth.

Pour into tall frost-chilled glasses and serve immediately.

1 cup fat-free vanilla frozen yogurt
3/4 cup fat-free milk
