Key-Lime Banana Smoothie

1 container (6oz) of Yoplait 99% fat-free key lime yogurt
1 ripe banana, peeled and sliced
1/2 cup fat free milk
1 tbsp fresh lime juice
1/4 tsp dry lemon lime drink mix (like Kool Aid mix)
1 cup vanilla frozen yogurt 

Place all of the ingredients in the blender, blend it up, and serve. This is soooo good! I love adding ice to mine to make it extra frosty. Sometimes I will substitute fat-free milk for almond milk to save a few calories.
