Add half of the butter and all the bread ingredients (not dressing ingredients) are added into a bowl and mixed.

Add the rest of the butter after 10 minutes and continue to mix.

When the dough is done mixing, it will look and feel smooth and stretchy as shown below.

Put the kneaded dough in a warm place to proof until it is about 2 and a half times bigger.

After the dough is fermented, take out and divide it into 12 portions, round and continue to rest for 15 minutes.

After it is done resting, use a rolling pin to knead the dough into an oval shape.

Then turn the oval dough over and roll it up.

When it is completely rolled, push the ends in, and the seals needs to be pinched, otherwise it will open when baked.

Put the rolled dough seam-down on the baking tray and move to a warm place to continue the rising again until the dough becomes 2 times larger.

Bread dough is brushed with a layer of egg wash. Preheat the oven to 170 degrees and then bake the dough for 10 minutes.

Take the pan out to let cool. Then cut down the middle, put in the lettuce leaves, squeeze some ketchup (or your favorite sauce), then add the grilled or fried sausage and enjoy this delicious snack!
