Lemon-Blueberry Frozen Yogurt

I don't know about everyone else, but my ice cream maker is one of my most seldom-used appliances.  I'm not sure why, since it's pretty hard to go wrong with ice cream.

The Ingredients:
24 oz vanilla soy yogurt
1 c sugar
3/4 c fresh lemon juice
1/4 c soy creamer
2 T lemon zest
1 c blueberries

The Process:

1. Whisk together all ingredients EXCEPT blueberries.
2. Freeze according to your ice cream maker's instructions, stirring in blueberries towards the end of the freezing time.
3. Serve immediately for soft-serve style frozen yogurt, or freeze in an airtight container for a firmer texture.
