Quick "homemade" frozen yogurt

I hardly think that this qualifies as a recipe, but it's a trick that my mom taught me for when I'm craving some Pinkberry.  Just combine some plain yogurt and frozen fruit (and sugar if desired) in a food processor or blender and puree until smooth.  I'd say to use about a 2:1 ratio of frozen fruit to yogurt so that you end up with a thick consistency and not a smoothie.  This was mango and it was delicious.  I even gave Noah a few bites and he absolutely LOVED it.  It's a great quick, easy, healthy, refreshing summer dessert that is much cheaper than going out for yogurt.  Of course, Pinkberry is as much about the toppings as it is the yogurt, so top with your favorite fresh fruit, nuts, granola, shredded coconut etc.
