Heat a large Dutch oven over medium-high heat. Add olive oil and heat 30 seconds. Add sausage and cook, stirring occasionally, until browned, about 5 minutes. Transfer sausage to a large bowl. Add chicken, sprinkle with 1/2 teaspoon of the salt and 1/4 teaspoon of the pepper, and cook and stir until just cooked through, about 5 minutes. Transfer chicken to the bowl with the sausage. Add bell peppers, celery, onion, jalapeno and remaining salt and pepper to Dutch oven, and cook over medium-high heat until vegetables start to soften, about 8 minutes. Add garlic and 2 tablespoons of the hot sauce to the pan and cook 3 minutes more. Return the meat mixture to the pan. Add bay leaves and tomatoes and cook and stir, about 5 minutes. At this stage the mixture can be refrigerated for several hours or overnight. When ready to proceed, heat meat mixture over medium-high heat. Stir rice into hot meat mixture and cook 3 minutes. Add the stock and bring to a boil. Reduce heat and simmer 30 minutes. Stir in remaining 2 tablespoons hot sauce and let sit covered for 10 minutes. To make tailgating as easy as possible, bring your meat mixture already prepared, ice packs, 2 boxes of chicken stock, a resealable bag of rice and a bottle of hot sauce all packed into your tailgating stock pot. This recipe easily doubles for a large crowd.
