Preheat dutch oven and add oil. Add onions, salt, pepper and okra. Cook on low heat to smother, stirring constantly. Okra will get slimy; keep cooking. When the okra is no longer slimy, add a little water at a time to get somewhat thick, but not "gloppy". Add diced tomatoes and chicken. Simmer until meat is cooked. Serve over warm rice.
