Easiest thing to do would be to get some store-bought teriyaki sauce and saute the ground beef in it, cook the noodles, and combine the two. You can add some finely minced garlic to the mix for a little extra flavor.
Or if you don't want to use a pre-mixed sauce, combine some soy sauce and honey (use as much or as little honey as your tastebuds prefer) with some finely minced ginger. Add finely minced garlic if you like, and/or some bean sprouts. Saute the ground beef in it and combine with the cooked noodles.
