In a bowl, mix the flour, salt, and instant yeast. Add in the warm water and oil. Knead everything together until the dough is smooth, elastic, and slightly tacky. (To adjust the dough if it is a little too dry: sprinkle in a little bit of water. If the dough is too wet, add a small amount of flour) Note 2
Cover the bowl with a lid or damp towel. Let the dough rise until it has doubled in volume, around 1-1.5 hrs.
Punch down the dough to remove the large air bubbles. Roll the dough out into a large rectangle around 1/3" thick.
Spread a thin layer of oil across the surface of the dough. Sprinkle the chopped green onions and five spice on top.
Roll the dough up from the long end to create a log. Then, roll up the log sideways into a spiral or snail shell shape. Note 3
Flatten the dough out to your desired thickness. The thicker the bread, the longer it will take to cook.
Sprinkle a small amount of water on the surface of the dough. Add your desired amount of sesame seeds on top. Use your hands or a rolling pin to press the sesame seeds into the dough to ensure that they adhere
Cover the bread and let it rise for around 30 minutes or until noticeably puffy.
