One of my favorite drinks to make (sans alcohol, of course) is a berry smoothie. It's such an easy recipe - I know you'll love it. I keep frozen berry puree in my freezer, and when I'm in the mood for a smoothie, I can either chop off a chunk of the frozen brick or thaw the whole bag.
1/4 c. berry puree
2/3 c. (6 oz.) vanilla yogurt - I use Dannon Light n' Fit
6 ice cubes
1/2 packet Sweet n' Low (optional)
Whip all ingredients in a blender. I add the Sweet n' Low if the berries weren't super sweet and ripe when I pureed them.
