Add the peaches to a food processor, and process until mostly smooth. Add the maple syrup, yogurt, vanilla, and salt to the peaches, and continue to process until smooth and creamy. Place peach mixture in the fridge for 1-2 hours.
Stir the chilled mixture, and freeze in your ice cream machine according to the manufacturer’s directions. When finished, the frozen yogurt will be soft but ready to eat. For firmer frozen yogurt, transfer to a freezer safe container, and freeze at least 2 hours.
Notes
Can be stored in an airtight container in the freezer for up to 1 month
