Wear gloves for this part, chop Habaneros (I don't remove the seeds). Heat oil and cook onions, peppers and carrots for 5 minutes or until onions are tender. (fumes may be strong for those that have breathing problems). Stir in Mangos, vinegar, ketchup, lime juice and sugar. Heat to a boil. Stir occasionaly. Reduce to a simmer and let it simmer for 30 minutes.
