In salted boiling water, cook fava beans for about 4 minutes or until tender but still firm. Drain and transfer them to a bowl with ice cold water. Peel off the skins by pinching the beans and discard the outside layer.

Blend fava beans with arugula in a food processor until very coarsely chopped. Add remaining ingredients and pulse the food processor until you obtain a smooth purée or preferred consistency.

Taste and adjust flavors to your liking.
