If the pan looks dry, warm the last tablespoon of olive oil in it. Otherwise, just add the chorizo, and cook for 2 to 3 minutes, until it’s beginning to crisp. Add the onion and garlic, and cook, stirring, until softened, about 5 minutes. Add the cumin and paprika, and cook for 1 minute. Add the wine, and cook until it’s almost all reduced, 1 to 2 minutes. Add the tomatoes, plus 2 teaspoons salt. If they’re fresh, cook for 5 minutes, until they begin to lose their shape and look a little saucy; this may happen 1 to 2 minutes sooner with canned tomatoes. Add the rice, and cook for 1 to 2 minutes in the tomatoes and spices. Nestle the chicken thighs back into the pan, including any juices that collected on the plate. Pour in the broth, and bring to a simmer. Reduce the heat to the lowest possible simmer, and cover the pan. Cook for 20 to 25 minutes, until the rice has absorbed the liquid and is tender, and the chicken is cooked through. (If your rice is undercooked, add ¼ cup water and cook for another 5 minutes.)
