Cut the Brussel sprouts in half. Sprinkle with salt. Place in a heat proof dish and steam over briskly boiling water for about 10 minutes or just until tender. Take out of the steamer and cool.
While the Brussel sprouts are in the steamer, toast the sesame seeds in a small oil-free frying pan until they glisten with oil. Tap the sesame seeds into a small plate and cool.
In the same frying pan, toast the salted cashew nuts. Transfer to another plate and cool.
Heat the cooking oil in the frying pan. Fry the cubed saba banana until golden. Scoop out, transfer to a plate line with kitchen paper and cool.
Dice the mango and avocado.
Toss everything together and sprinkle with parsley.
