My entire family got so hooked on choripan during our holiday in Buenos Aires last year so it didn't take much to excite them on our meal this evening. It is really a simple sausage (chorizo) sandwich with chimichurri on a toasted bun. Chimichurri is my favorite accompaniment for almost anything - steaks, burgers or even a dip for chips. And it's a piece of cake to make - chopped parsley, garlic (tons), red wine vinegar, olive oil, oregano, red pepper flakes, salt and pepper. I then grilled the sausage mariposa style (butterfly), in this case, I used spicy Italian sausage, so it laid flat on the bun. I then slapped the sausage in between a mini baguette overflowing with chimichurri and finished it in a panini press. I tossed a simple green salad with a garlic vinaigrette. Yum and done!
