Last year at one of our staff Goodie Days I made this. It's so quick and easy all I had to do ahead of time was cut up the angel food cake and strawberries. Then when I got to school I assembled it and VOILA! Easy, healthy, sweet.
2 quarts ripe strawberries, quartered
1 angel food cake, diced
1 tub light vanilla yogurt (I use Dannon Light and Fit)
Layer ingredients in a trifle dish or bowl as follows: angel food cake, strawberries, yogurt, repeat.
It's as easy as that.
quick tip: I like to quarter my strawberries the night before and stir in just a tiny bit of Sweet and Low to marinate.
