Directions

1. In a large stockpot, combine chicken and enough cold water to just cover the chicken. Add 1/2 onion, 3 whole garlic cloves, and 2 tablespoons salt. Bring to a boil over high heat; reduce heat to medium, and cook for about 1 hour. Allow to cool. Remove chicken from pot; remove meat, discarding skin, and shred. Set aside. Strain broth, discarding solids. Set aside.
2. In a large Dutch-oven, combine 3 cups of the chicken broth, tomatoes, allspice, thyme, basil, oregano, and hot sauce over medium heat. Bring to a simmer, breaking up the tomatoes with the back of a wooden spoon.
3. Meanwhile, heat 3 tablespoons vegetable oil in a large skillet over medium-high heat. Add celery, chopped onions, bell peppers, and minced garlic. Cook until softened, 5 to 7 minutes; add to Dutch-oven.
4. In the same skillet, heat remaining 1 tablespoon oil over high heat; add sausage, and cook until heated through, about 5 minutes. Transfer to Dutch-oven. Add shredded chicken, rice, and remaining 2 tablespoons salt; simmer, covered, for 15 minutes. Add shrimp, and simmer, covered, until rice is tender, about 5 minutes. Remove from heat; let stand for a few minutes, and serve.
