This is a great Thai flavor, although it may not be traditional, but to me it still adds all the same flavors of the lime, garlic, and heat from the red pepper. This is NOT a saucy dish but lighter in calories... but still has tons of flavor. If you don't want to use shrimp for this you could easily substitute chicken. The sesame noodles to me are key, it really makes the difference, but you could use vermicelli or spaghetti if need be. I found my sesame noodles right in my local grocer.
