In a bowl add warm water, sugar, salt and active dry yeast. Mix everything well
1¼ cup warm water, 2¼ teaspoon active dry yeast, 1½ teaspoon salt, 1 teaspoon sugar
Rest covered for 10-12 minutes. The yeast should bloom by then. Open the cover and keep ready.
In the base of the stand mixer, add all purpose flour, unsalted butter, salt and the bloomed yeast mixture.
3 cups all purpose flour, 3 tablespoon unsalted butter
Run the mixer on medium speed till everything comes together.
Keep mixing on high speed till the dough is soft and without cracks.
Roll the dough ball tight and transfer it to a greased bowl.
Rest covered for an hour. The dough should double by then.
Punch down the dough and smoothen it well. Also, line a triangle bread mold for the grilled sandwich with oil or butter and rest on a greased tray.
Transfer the entire dough into the mold and press it down using light hands, spreading it throughout the mold.
Cover with another baking tray or plate and let it double. In about an hour, the bread dough will rise to the brim of the mold.
Place in a preheated oven at 400 F and bake for 20-22 minutes, till the top is crisp and the mold sounds hollow when tapped. Then remove the bread.
Let the bread cool down a little and remove from the mold.
Then let it cool down completely. Place on a chopping board.
Make equal size thin slices and keep ready. Also, keep all the vegetables and other add-ins ready.
