From SFWeekly they mentioned Rocky's Frybread - set up in front of Fabric8. He's from a reservation in Shiprock, NM. Vegan, organic dough, fried, then honey & powdered sugar on top - you can ask for it without honey to be vegan.
He might have Hatch Valley green chiles and Navajo tacos
To find him:
On the streets of the Mission: Amnesia & Fabric8
Monday nights in front of El Rio 9pm
No set prices for his food - He accepts donations
Anyone try it yet?
3158 Mission St, San Francisco, CA
