In a very large roasting pan measuring approximately 21 by 17 by 7 inches with handles on both sides, heat the oil over medium-high heat. Add the onions, bell peppers, celery
, garlic, Essence, salt, pepper, cayenne and bay leaves, and cook, stirring, until the vegetables are very soft and starting to turn golden, about 15 minutes. Add the sausages
and cook, stirring, until they start to brown on the outside, about 7 minutes. Add the turkey legs and meat and stir well. Add the tomatoes
and their juices and cook, stirring, for 5 minutes. Add the rice and stir well to incorporate and coat evenly. Add the water, stir well to combine, and bring to a boil. Reduce the heat, cover tightly, and cook without stirring until the liquid is absorbed and the rice is tender, 35 to 40 minutes, adding more water as needed if the liquid is all absorbed before the rice is tender.
Remove from the heat and let sit for 15 minutes before serving.
Remove the bay leaves. Stir in the green onions and parsley, and serve hot.
