Cook cranberries very gently in sweet rice wine vinegar until skins pop. Monitor fluid level carefully.
Set aside to cool.
Combine all other ingredients in a serving bowl, adding cranberries and persimmons last.
Serve over tacos or other grilled favorites.
Notes
* Substitute with finely chopped sweet onion if you prefer. **If you can't find Fuyu persimmons, you can substitute with mango to make a tropical mango and cranberry salsa.
