Chilled Berry Soup.  I read lots of different recipes and then melded them together to create this one.  Everything can be increased or decreased to find desired level of sweetness and consistency.

3 cups frozen unsweetened strawberries
1 c frozen unsweetened raspberries
1 container plain (or vanilla or fruity) ff yogurt
1/4-1/3 c sugar (to taste)
1/3 cup orange juice (can be increased/decreased to taste)
a little bit of sour cream.  mmmmm!!
dash of cardamom (or ginger or Cinnamon since I don't have cardamom)
diced sour cream pound cake (bundt cake or pudding cake or whatever you call it)

liquefy in the blender and serve chilled.  It can be frozen and re liquefied- but it needs to be a little warmer to make soupy.  Top with pound cake croutons!!
