Healthy Slushie Recipe for 7-11 day

It's July 11th, also known as 7-11 day in the U.S.  (If you're not from here, 7-11 is a chain of gas stations famous for selling junk food and slushies.)  If you're experiencing a hot summer, a slushie is a great refreshing treat.  However, the ones at 7-11 are packed with sugar, food coloring, and who-knows-what chemical preservatives.  Here's a simple recipe for a healthy slushie you can make at home:

1 to 1 ½ cups frozen fruit, slightly thawed (I like raspberries the best)

2 cups seltzer water

Add ingredients to a high-speed blender and blend until the fruit is fairly liquefied.  It's as easy as that to make a tasty, carbonated, refined sugar-free frozen drink to quench your thirst.
