Heat a skillet over medium heat. Add sesame seeds; cook, stirring occasionally, until toasted, about 5 minutes. Transfer to a large plate.
Shape fava bean mixture into balls. Roll in sesame seeds to coat.
Fill a large saucepan 1/4 full with oil; heat over medium heat. Fry fava bean balls in batches until golden brown, 3 to 5 minutes. Drain on paper towels.
