Peel and core the fresh pineapple, then cut into strips that could fit in the wide chute of Fretta JC01 Pro Max Slow Juicer. Next, wash the kale leaves thoroughly, and peel the ripe banana.
Turn on your Fretta JC01 Pro Max Slow Juicer. Feed the pineapple strips, kale leaves, and banana through the wide chute of the juicer. Opt for Hard Mode and juice the pineapple stripes, and then switch to Soft Mode to juice kales leaves and banana in order.
After juicing, give the mixture a gentle stir to combine the flavors. Pour the refreshing juice into a glass, and if you desire, add ice cubes. Enjoy!
