A while back I came across this somewhere at BBC Food. A quick frozen yogurt which didn't require an ice cream machine, just a food processor. The idea is similar to the frozen banana dessert I posted recently, only this time you combine frozen fruit with Greek yogurt and a touch of honey.
1 cup Greek yogurt (I used 2%)
about 2 cups frozen cut up fruit and/or berries
1-3 tablespoons honey, depending on the tartness of the fruit you are using
Place everything into the bowl of a food processor and pulse until you have a smooth mixture.
If the mixture isn't firm enough, add a bit more frozen fruit and process again.
Garnish with fruit or berries, if desired. Serve.
