In a large bowl, mix together warm water, yeast and sugar. Add in salt, vegetable oil and flour then mix with a wooden spoon or a kitchen stand-up mixer to form a dough.

Place the dough on a floured board and knead for about 5 minutes until smooth. Let the dough rise in a warm place until doubled in size for about 1-2 hours.

Punch the dough to remove air. Cut the dough into four equal parts. Shape each part into a long log. Use a knife to create 6-8 diagonal lines (about half inch deep each) across each loaf. Place the loaves on greased baking sheets/trays and let them rise in a warm place for about 30 minutes.

Bake in a preheated oven at 350 degrees F (180 degrees C) for about 25 minutes until the bread is nice and golden brown and hard on the outside. Brush with melted butter as soon as they are out of the oven.
