With the exception of using merguez (a spicy Moroccan sausage) instead of the chorizo, and a generic Israeli sausage instead of the Italian, I didn't really make any major substitutions. This is a great way to clean out your vegetable drawer. I just added a little fresh coriander (since that was sitting in there as well). The only change I would make would be to add some onion. It was great for dinner and even better tossed into some Tupperware and nuked at the office the next day.
