Out of curiosity, when you say crispy noodles, do you mean pan-fried noodles?
All the noodles we eat are dried and boxed, except for udon noodles which can be found frozen.
If I wanted to make lo-mein I'd probably look for spaghetti and soy sauce, sugar, and maybe some sort of oyster sauce (or fish sauce, or Hoisin sauce...throw whatever we have in our pantry) to taste. And yeah, I would probably use sesame seed oil to mix and fry.
As a warning, we've never really tried to make Chinese food except for maybe any overlap there might be into Korean food (scallion pancake, a bunch of egg dishes, rice porridge, etc).
