At home: Place the freeze dried yogurt in a small food processor or spice grinder and blitz it into powder, then place in a zip top bag with the dried fruit. Package the granola separately.
In camp: Add ¼ cup cold water (more or less depending on preferred consistency of the yogurt) to the powdered yogurt and fruit. Let it rehydrate, stirring occasionally, until creamy and smooth — about 5 minutes. Top with the granola.
