Finely chop the cilantro and mix it with the lemon juice. Finely cut 2-3 sliced of radish and rub the lemon/cilantro mix over it. Place the beans in the lemon/cilantro mix, and let it sit for 5 minutes. Meanwhile, heat your salmon gently in your microwave until it’s warm. Place it on the bread. Lay out the radish and fava beans on top, and grind a puff of pepper on top. Finally garnish with a slice of Parmesan cheese.
