This was a bit of a strange combination that turned out just amazing!! The flavors are strong and vibrant, complimenting the chicken nicely. You could probably use left over or rotisserie chicken to speed things up, although I cooked up some breasts for this sandwich. For the chorizo, you want to use the kind that you get at the deli and has already been cooked and cured, not the raw stuff. The amounts are really just estimates, since it'll vary depending on the size of your bread. For grilling the bread, use a panini press, a Foreman grill, or even just a pan to toast the bread. I recommend the bread have a strong enough texture, like a ciabbata, saloio, or my favorite is the Tuscan pane from Trader Joes.
