One of my favorite ways is with a smoothie. Fresh fruit is abundant and ripe this time of year. When it's combined with juice, yogurt, and ice it is perfectly refreshing on a hot day and a great afternoon snack if you feel your energy dipping. Add a bit of flax or other additional nutrients, too, if you'd like.
Smoothies are also a great way to get kids involved in the kitchen. Use the proportions in this recipe as a base for creating other fun flavor combinations. Kids love to help pick what fruits to add in, and mine love watching the blender whirl.
You can also take a smoothie recipe and fill popsicle molds with the drink and freeze them for super healthy popsicles. If you don't have a popsicle mold, try Dixie cups and popsicle sticks, which can be found at most craft stores. Fill each cup with some of the mix, cover with foil, and insert a stick. Freeze until solid. When frozen, remove the foil (that was just to help the stick stand up straight), and peel the cup away.
