Let this stand aside for a bit, and in the meanwhile, melt the margarine in a 9" x 13" pan in an oven, at the set temperature of 425° F. Once the margarine is all molten, remove the pan from the oven, with oven mitts on, and mizzle the rest of the salt and garlic powder into it. Place the dough into the pan, and use a sharp pizza cutter to make thin dough strips. Start by cutting the dough into half, lengthwise and breadth wise, and then go on halving and further halving all the sections lengthwise, until you are left with plenty of slim long strips.
