Recipe adapted from Luke Tsai, on Taste.

Ingredients
Noodles - whatever you have, from spaghetti to Chinese egg noodles

Toppings:
Cucumber, julienned or grated
Carrot, julienned or grated

Cooked ham, julienned
(Options: shredded cooked chicken or turkey, bell pepper, bean sprouts, water chestnut, jicama, snow peas, shredded cabbage, fresh parsley or cilantro, etc.)

Sauce (for 2-4 servings)
