Cut the breadfruit, remove the seeds in the core, and peel. Boil in salted water with a little onion and oil, over high heat until tender and drain. Meanwhile, melt the butter in a frying pan and lightly brown the onion rings. Add the garlic, tomatoes, parsley, lime juice, salt, and pepper. Continue to sauté for a couple of minutes. Add the water, bring to the boil and simmer for 5-10 minutes. Slice the cooled breadfruit and place it in a serving dish. Pour the butter sauce over the breadfruit. Garnish with chopped fresh parsley. Serves 4
