Stawberry-Limeade Smoothie

I tried this recipe today from the Biggest Loser Cookbook. They were really good.

1 1/2 cups frozen strawberries
6 ounces fat free key lime yogurt
1/4 cup fat-free milk
zest of one lim (about 1 1/2 tsp)
2 tbsp freshly squeezed lime juice
splenda to taste

In a blender with ice crushing ability, combine the strawberries, yogurt, milk, lime zest and juice, and sugar substitute. Blend on high speed until smooth.

Makes 1 serving.
