Once the rice is cooking, place a large soup pot over medium-high heat with 2 turns of the pan of EVOO. Add the andouille and cook until brown and crispy, about 4-5 minutes. Add the celery, green bell pepper, onion, bay leaf, sweet potato and hot sauce to taste. Cook about 5 minutes, stirring every now and then, until onions start to get tender. Add black-eyed peas, stewed tomatoes and remaining quart of chicken stock. Turn the heat up to high and bring up to a bubble. Once bubbling, lower heat down to medium and simmer for 10 minutes, until the sweet potatoes are tender.
To serve, place a large scoop of rice in a soup bowl and add enough Hoppin' John to almost cover the rice. Give it a stir to combine. By cooking the rice separately, you never run the risk of the rice getting mushy on you and it will be waiting for you whenever you are ready to eat!
