Cheater's Frozen Yogurt
What am I taking about? It's a dish that I've dubbed Cheater's Frozen Yogurt.
All it is is frozen berries mixed with some plain yogurt and a bit of sugar sprinkled on top. The berries freeze the yogurt when the two come into contact! The trick to getting this just right is in the proportions. Now, I don't measure this and I don't really recommend expending the extra effort to do so. Use 2 parts of frozen berries and 1 part yogurt. Put the yogurt into a bowl with a pinch or two of sugar two sweeten it, then add the berries and stir to combine. After about 30 seconds or so, the yogurt will be slightly frozen and you can enjoy it!
Blueberries are the best for this because of their small size, making them very easy to stir into the yogurt. If you use other fruit, you may want to consider chopping it up a bit first.
