Preparation Preheat oven to 350°F with racks in upper and lower thirds of oven. Butter a 3-quart shallow baking dish. Crumble corn bread into 1/2-inch pieces, spreading out in 1 layer in 2 large 4-sided sheet pans. Bake, stirring occasionally, until dry, about 20 minutes. Cool completely and transfer to a large bowl. Meanwhile, cook chorizo in oil in a 12-inch heavy skillet over medium-high heat, stirring occasionally, until crisp, 1 to 2 minutes. Add onions, celery, garlic, oregano, and 1 1/4 teaspoon salt and sauté until vegetables are softened, about 10 minutes. Add to corn bread. Whisk together broth and egg, then pour over stuffing and toss well. Transfer to baking dish and cover tightly with buttered foil. Bake in upper third of oven 1 hour. Remove foil and bake until top is golden, about 15 minutes more.
