In a previous post (ISO ethnic gems....)I asked for any recs for pambazo de tingas or taco de suadero in the northern OC area. Lacking any feedback for this geographic area, thought I would extend the parameters. I've searched the SF Board trying to find the image that set me off on this quest, without any luck. I found and great thread from 2001 discussing this great sandwich but couldn't find the pic that inspires my search. Southbound on Wed AM, any help greatly appreciated. From my feeble recollection, similar to a torta but on a round roll, covered with a dry cheese and crema.
