Frozen red grapes are one of my favorite treats during the summer. Once frozen, the grapes become super sweet - like tiny bite-sized frozen desserts. They are low-calorie and so refreshing and delicious. Just rinse the grapes and put them in the freezer for a couple of hours.
You can also fill a tall glass with frozen grapes and pour Diet Sprite over them for a slushy low-calorie drink. Add a shot of grenadine for color (optional).
