Place turkey in a steamer over boiling water. Sprinkle thyme over it. Cook for 6 minutes.
Add sweet potatoes, carrots and cranberries to the pot with the turkey. Cook another 6 minutes or until turkey is cooked though and vegetables are tender.
Cool turkey for several minutes, so the juices can redistribute and then cut into cubes.
Place all the ingredients in a food processor and puree. Add some of the water from the pot, a tablespoon at a time to make smooth.
