Chop banana and peach into small chunks. Slice off the tops of strawberries. Combine in a blender and blend until smooth. Add in yoghurt and blend again. Enjoy!
This is just how I personally make mine. You can add more or less of any of the fruits until it tastes just the way you want it.
If you're making it for a large group of people, just double, triple, or quadruple the amounts. This seriously takes less than five minutes to make, so if you're the type to skip breakfast because of your schedule, you no longer have an excuse! :)
