Wash and cut your matumbo as you desire, boil on high heat for 1hr 45mins since matumbo is hard it takes time to cook well....when it has cooked well make sure all the water has evaporated add in onion with cooking oil let them fry for about 3mins......add tomatoes, paprika and salt stir and let them cook well..........for greens just stir fry with onion, oil and a little salt to taste.......now serve your matumbo and greens with Ugali...!!!
