Frozen Yogurt Covered Blueberries I'm a big fan of freezing grapes for a quick grab-n-chew healthy snack when I'm working away in the summer. It keeps me cool, the natural sugars give me a boost of energy, it's loaded with antioxidants and some fibre too... goodness all around. To vary it up sometimes, I like to make these frozen yogurt covered blueberries. It's an incredibly easy-to-make recipe it's also a great snack option for warmer months.
