Heat 2 Tablespoons olive oil or butter in a frying pan and add ground chicken breast.
Cook for 2 minutes over medium heat, then add one small finely chopped onion and cook for 2 more minutes.
Add chopped parsley or cilantro, season with salt and pepper and mix until the ingredients are well combined.
Set aside while preparing the dough.
Divide the dough into 8 equal pieces. Form each piece into a ball.
Lightly flour the working surface and start forming your chicken buns by rolling each ball into a 4 inch circle and placing one full Tablespoon of the filling in the middle of each circle.
Gather edges of circles over the filling, and pinch them together to seal.
Place the buns on a greased baking tray, sealed side down.
Brush each bun with lightly beaten egg and sprinkle with sesame seeds.
Bake at 355F for 30 minutes until the buns turn golden brown.
Brush lightly with melted butter as soon as you take them out of the oven.
Transfer onto a serving dish and enjoy!
