If you're trying to consume less ice cream and/or frozen terrible/tasty things - you definitely should try this.
All you need is a cup of your favourite kind of yogurt (I use the no-fat Chobani peach one), a pack of fresh blueberries and two toothpicks (you definitely need the toothpicks or this becomes unbearably messy). Get a cookie sheet pan out and put down some tin foil, then stick a berry with a toothpick and dip/swirl in the yogurt cup and use a second toothpick to push it off onto a cookie sheet. Coat all of the blueberries and then place the cookie sheet in the freezer. After an hour you can pop them off the cookie sheet with a fork/spatula and put them into plastic baggies.
Can't tell you how good these taste.
