We had these with Sunday brunch a few weeks ago (to use up some leftover champagne) and they were really good. Since you pour the champagne on top of the smoothie mix, you can make up and serve to kids and adults.
Champagne Strawberry Smoothies
2 c. chopped fresh strawberries
1 c. any flavor low-fat or nonfat yogurt -- I used Greek Yogurt, plain w/honey
Splash of OJ
Place yogurt, strawberries & oj in blender and blend until smooth. Pour into glasses and top with champagne.
Garnish with strawberry or mint.
