Wrap the peeled matoke in banana leaves or foil and steam over simmering water for 35 to 40 minutes, until soft.
While the matoke steams, heat the oil in a pan and soften the onion for 2 to 3 minutes.
Add the tomatoes and green pepper, and cook until softened, about 5 minutes.
Stir in the curry powder, then add the cooked beans and a splash of water. Simmer for 10 minutes, stirring occasionally.
Season the bean sauce with salt.
Mash or lightly crush the steamed matoke and serve with the bean sauce and avocado slices on the side.
