Chop and prep all ingredients. If the chorizo sausage is wrapped in a casing, score the casing and remove it before slicing. You can remove the shrimp tails or leave them on for visual appeal.
Place a large sauté pan over medium heat. Add the Zatarain's® Black Beans & Rice Dinner Mix, water, frozen corn, and butter. Cover the sauté pan and bring to a boil. Then lower the heat and simmer for 20 minutes.
Add in the shrimp, chorizo, and diced bell pepper. Stir well. Cover and simmer another 5 minutes. Remove from heat. (Do not let the shrimp cook longer than 5 minutes.)
Toss the rice. Top with fresh sliced avocado, pico de gallo, queso fresco, and lime wedges. Serve warm.
NOTE: This recipe can be doubled in an extra large sauté pan to feed a crowd.
