Combine the filling by folding together the chicken, spinach, mozzarella, and feta. Season with salt and pepper.
Whisk the eggs on a plate. Dip each rice paper sheet into the egg mixture for a few seconds, then lay it flat on a lightly oiled cutting board.
Spoon the filling in a line across the rice paper sheets and roll tightly into a cylinder.
Gently curve the roll around itself to form a spiral.
Brush the outside with more egg wash and sprinkle with sesame seeds.
Bake at 400°F (205°C) for 15–20 minutes, until golden brown and crisp.
Serve warm with lemon wedges.
