Note: Lime may not be your typical smoothie flavor, but maybe that is why I like this one. It is different and I like to try unique things. Most times they are the most refreshing!
1/2 cup lime (peeled and sliced)
3/4 cup low-fat milk
1 cup lime sherbet
1/2 cup raspberries
2 cups ice
Blend and serve.
You can substitute key lime yogurt for the sherbet for a smoother, albeit, slightly different taste.
