Heat oil in a dutch oven on medium heat. Add onion, celery and chorizo sausage meat. Use a wooden spoon or spatula to break up the meat as it cooks. Stir often until the meat is browned, about 8 minutes.
Add the black beans, corn and garlic. Cook for 5 more minutes.
Add the remaining ingredients to the dutch oven and stir.
Cover with lid and bake in the oven for 45 minutes or until the rice has absorbed all the liquid.
