Look over the Soy Vay blends of sauces in your health-foods store or your TJ's. I wasn't sure how Jewish those guys are, despite the graphics on their bottles (okay, their site says they are pretty Jewish anyway), but I think they started out with bottled teriyaki sauce and then expanded into soy-sauce-plus this, that, and the other. There's bound to be something there that is fun over noodles-with-things, and I reckon most of the rest make a fine base for marinades and salad dressings.
