In a large stock pot, heat three tablespoons of oil or fat. I used bacon fat.
Add chopped celery, onion, and carrots to the pot and cook until the onions and celery are translucent. Sprinkle with salt and 1 tsp garlic powder as it cooks.
Add the cooked chicken, bacon, peppers, and green beans. Stir in until everything is heated through, letting the flavors meld. Add 1 tsp garlic powder and sprinkle salt on to taste.
Pour 6 cups of chicken stock into the pot and let simmer for at least a half hour. If you want it to sit on the stove for longer, add more stock than 6 cups.
About 10 minutes before you’re ready to serve the soup, add heavy cream and cooked rice. Bring the soup back to a simmer and serve immediately.
