Dissolve the yeast in the warm water. Add the salad oil and stir. Add the flour a little at a time, stirring and mixing until you have a well blended, manageable dough.
Place the dough in a large, oiled bowl, cover, and place in a warm area to rise for 1 hour.
Take the dough, knead it a couple of times and divide in two. Oil 2 baking sheets, and with your hands flatten the shape the 2 pieces of dough into 2 oblong loaves, 1/4 inch thick. With the edge of your hand make 3 ridges lengthwise on the surface of the dough.
Brush with the melted butter and sprinkle the sesame seeds on top. Cover with a towel and let rise in a warm place for 30 minutes.
Bake for about 20 minutes until golden. Serve warm immediately. Or, later, reheat the breads by wrapping them in foil and placing in a hot oven for 5 to 10 minutes. Yield: 2 breads. Do not freeze.
