To make the dressing, whisk together the remaining soy sauce, remaining garlic, rice vinegar, lime juice, sugar and sesame seeds. Add in 2 tablespoons of water and whisk well.
Cook the noodles according to package instructions. Drain. Taste the noodle to make sure it is done.
Grill or broil steak for 4 minutes per side, or until done to your liking. Let steak rest for 5 minutes, then thinly slice.
