In a bowl, season chicken with thyme, garlic, pepper, salt, black pepper and Worcestershire sauce. Mix to combine. This can be seasoned the night before.
In pot over high heat add oil. When oil is hot, add seasoned chicken and cook until browned, about 5 minutes. Add onion and tomatoes and cook for about 5 minutes. Add chicken stock and bring to a boil and cook for 5 minutes, then add cabbage.
Cook cabbage covered on medium for about 8-10 minutes until it has wilted and the liquid has reduced.
Remove from heat and serve warm over rice.
