As a side note, make sure the noodles are cooked al dente. If the noodles are too soft, they will be sticky and lumpy when stir-fried. You should also add some crushed red chilies. If you want to avoid the lumps, you should add the chilies a little at a time. If you want the dish to be spicy, you should use a schezwan sauce that is seasoned to taste.
