Melt the butter in a large pot over medium heat. Add the onion, bell pepper, and celery; sauté for about 5 minutes until softened.
Stir in the garlic, Creole seasoning, and salt; cook for an additional minute until fragrant.
Add the Polska Kielbasa and cook for about 5 minutes until browned.
Pour in the diced tomatoes and stir well. Add the rice, ensuring it’s evenly distributed.
Add chicken broth and bay leaf. Bring to a boil, then reduce heat to low, cover, and simmer for 20-25 minutes until the rice is tender.
Remove from heat, discard the bay leaf, and stir in hot sauce if desired. Serve warm!
