Crockpot Jambalaya

Got this recipe from Taste of Home but made a few changes to get it how I liked it. Seriously tasty and hubby thought it was even better the second day when all the flavors sort of melded together.

1 can tomato puree
20 oz. chicken broth (recipe called for 1 can but the consistency just needed more in my opinion)
1 can tomato paste
1 green pepper, chopped
1 onion, chopped
3 celery ribs, chopped
5 garlic cloves, minced
3 tsp. dried parsley flakes
2 tsp. dried basil
1 1/2 tsp. dried oregano
1 1/4 tsp. kosher salt
1/2 tsp. cayenne pepper
1/2 tsp. hot pepper sauce
1 pound chicken breasts cut into cubes
1 pound smoked sausage, halved and cut into 1/4-inch slices
1/2 pound uncooked medium shrimp, peeled and deveined
Hot cooked rice

In a 5-qt. slow cooker, combine the tomato puree, broth and tomato paste. Stir in the green peppers, onion, celery, garlic and seasonings. Stir in chicken and sausage.
Cover and cook on low for 4 hours or until chicken is tender. Stir in shrimp. Cover and cook 15-30 minutes longer or until shrimp turn pink. Serve with rice.
