A local recipe and I changed a few things around in several places. Originally, the recipe was for sopes not tostadas but I have problems frying the tortillas for making sopes (they always fall apart and/or lose their shape). Until I master that technique, it's tostadas for us. We buy a good quality, locally made/locally sourced chorizo that contains red wine vinegar and NO preservatives or other yucky stuff. I will try to post a copycat recipe for that one in the near future. The recipe is easily adaptable to vegetarian by subbing tempeh or similar.
