Lightly coat chicken pieces in seasoned flour. Heat 1 tablespoon oil in a large frypan over high heat. Cook chicken in batches for 5-6 minutes or until browned on both sides, adding more oil if needed. Remove from frypan and drain on absorbent paper towel.
Heat remaining oil in the same frypan. Add onions and garlic and sauté for 1 minute. Stir in Leggo’s Tomato Paste, oregano, bay leaf, tomatoes, wine, water and stock powder.
Return chicken to frypan, cover and simmer for 1 hour or until cooked through, stirring occasionally. Add olives in the last 10 minutes of cooking. Remove bay leaf before serving and garnish with basil.
