Pour warm water (temperature of 105 to 115 degrees F) into a small bowl and add the sugar and yeast. Quickly stir and let it sit for 5 minutes until the yeast is activated and foamy.
Grease a small square or rectangular baking dish.
Into a stand mixer bowl or large mixing bowl, combine the flour, salt, egg, olive oil, and yeast mixture. Knead with a dough hook for about 5 minutes or until smooth.
Divide the dough and shape it into 4 balls.
Place balls in the prepared baking dish and cover with a cloth. Allow rising for 30 minutes until almost doubled the size in a warm place.
Preheat oven to 400 degrees F.
Bake for 12 to 15 minutes until golden brown.
Brush with melted butter while still hot and serve.
