Any Roadfooders ever heard of this? It has been described as Mexican Pizza but it's more like nachos. I used to frequent a restaurant called La Choza 20-30 years go in Rogers Park (Chicago). It is hard to remember all of the ingredients but it was very tasty. Definitely chips, beans and cheese. The owners name was Sylvester and he was from Oaxaca. Don't know if it was his invention or a Oaxacan recipe. Can anyone help find the recipe?
