Scallion buns 蔥花麵包

This is a savory buns that I liked very much as a kid. The style and flavor is very simple, yet it's very delicious. The buns are very soft and doughy inside, topped with chopped scallions mixed with some black pepper, just to give you a little spiciness on the tip of the tongue. It's great for breakfast or afternoon snack. I was so happy that I could reproduce this snack from childhood.
