Shrimp & Chorizo Paella

My usual paella contains mussels, shrimps, chicken thighs and chorizo, following cook's Illustrated's recipe. This time I was going to skip mussels because since the vacuum-packed mussels I bought several months ago weren't impressive. Then, I found out that our online grocery delivery service couldn't bring chicken thighs because they suddenly became out of stock on our delivery day. Actually fresh parsley was also out of stock. I just had shrimps and chorizo. I wondered whether I should still make paella. I did after all, which led me to a great discovery. The result was wonderful and full of flavors! I didn't miss chicken, mussels or anything. I will go with just shrimp and chorizo in terms of paella from now on. Parsley will be an option, not necessary.
