In a small bowl, place about 2 tablespoons of the applesauce and the optional gelatin, and mix to combine. Set the gelatin aside to allow it to bloom in the applesauce (it will swell).
In a blender or food processor, place the strawberries and blend until smooth. Add the remaining applesauce, bloomed (optional) gelatin, yogurt, sugar and honey, and blend until very smooth.
Pour the mixture into the (prepared) bowl of your ice cream machine, and churn according to the manufacturer’s directions until thickened to the consistency of soft-serve ice cream.
Enjoy immediately, or transfer to a freezer-safe container and freeze for about 2 hours until more firmly scoopable.
If freezing for longer, allow the frozen yogurt to sit at room temperature for about 30 minutes before serving. It will be easier to scoop.
