This is what your local Chinese restaurant's "sesame noodles" wish they could be... and probably a lot closer to what they originally were. Other additions/substitutions might include 1/2 c of any of the following: a plain Japanese-style omelet (tamago), cut in thin strips; corn kernels, frozen and thawed or fresh (if fresh, blanch for 1 minute first); cucumber, seeded and julienned; bell pepper, julienned and blanched for 1 minute; cooked chicken; chopped shrimp; roast pork; shredded duck. Avoid rice noodles, which tend to get hard when cold, or udon, which are simply too thick.
