Cook rice with usual amount of salt (do not overcook). Then set aside in a large thick pot. Cook, on low heat, diced onion and chopped pepper in a small amount of cooking oil until limp. Then add tomato juice or sauce, salt, pepper and oregano, as well as meat. Cover pot and simmer slowly for 10-15 minutes, stirring occasionally. Add this mixture to rice and stir gently till mixed. Put on low heat and cook until liquid is absorbed by rice and mixture is fluffy. Do not cover tightly, lid should be ajar. Fluff gently. It gets sticky easily!
