This is a great dessert to put together with kids, as my five-year-old made it entirely by herself (with me watching her cut the strawberries).  It's also very colorful and perfect for the Fourth.  Here's what you need:

Strawberries and blueberries (fresh); the amount is optional, but you may want to use about four strawberries and a 1/4 cup of blueberries per serving.

Vanilla low-fat yogurt

Colorful sprinkles

Wash and drain the strawberries and blueberries.  Core the tops of the strawberries and slice them lengthwise.  Using short glasses, first fill with blueberries, put a few spoonfuls of yogurt over them, then fill with sliced strawberries, and put a few spoonfuls of yogurt over them.  Top with sprinkles or any other topping you prefer.  You could also substitute whipped cream for the yogurt.  Have fun!
