Heat 1/4 cup of the olive oil in large heavy nonstick pot or Dutch oven over medium-high heat. Season the chicken with 1 teaspoon of the salt. In a bowl combine the Essence with 1/2 cup of the flour and stir to combine. Dredge the chicken pieces in the seasoned flour mixture and shake to remove any excess flour. Brown the pieces, in batches if necessary, until golden on all sides, 10 to 12 minutes. Transfer to a plate and set aside.
Stir in the onions, bell peppers, celery, remaining 1/2 teaspoon of salt, crushed red pepper flakes, cayenne, and bay leaves. Cook, stirring occasionally, until the vegetables are soft and lightly golden, about 5 minutes. Add the remaining 3 tablespoons of the flour and cook, stirring, to cook the flour without browning, 1 to 2 minutes. Add the tomatoes, chicken stock, Worcestershire, and pepper sauce.
Return the chicken to the pot, increase the heat under the sauce to medium-high and bring to a gentle boil. Reduce the heat to medium-low. Simmer uncovered, stirring occasionally, until the chicken is fall-from the bone tender, about 1 1/2 hours. Remove and discard the bay leaves.
To serve, spoon the rice onto plates, top with the chicken and sauce, and garnish with the green onions and parsley.
Combine all ingredients thoroughly.
