Preheat oven to 350°F with racks in upper and lower third positions. Line 2 large baking sheets with parchment paper.
Stir together oats, wheat bran, figs, pecans, benne seeds, sugar, lemon zest, cinnamon, and salt in a large bowl.
Whisk egg whites in a medium bowl until frothy, about 15 seconds. Add butter and honey to egg whites; whisk until well combined.
Fold egg mixture into oat mixture until oats are well coated.
Spread granola mixture on prepared baking sheets. Bake until granola is golden brown, about 20 minutes, stirring and rotating baking sheets halfway through bake time.
Let cool completely, and serve with yogurt and fresh fruit, if desired.
