Soba Noodle Salad with Grilled Flank Steak

In a large bowl, whisk together soy sauce, sesame oil, rice vinegar, Sriracha, honey, garlic, and ginger. Slowly whisk in oil until combined. Place steak in a shallow baking dish and pour 1/3 of soy mixture over steak. Let sit 10 minutes. Bring a large pot of water to boil. Cook soba noodles according to package directions, then drain and rinse with cold water. In a large bowl, toss noodles with carrot, cucumber, 1/2 of scallions, and sesame seeds. Pour remaining soy mixture over noodles and toss gently to combine. Heat a lightly oiled grill pan or grill over high. Remove steak from marinade and season with salt and pepper (discard marinade). Grill steak 5 minutes per side for medium. Let rest 5 minutes and thinly slice on the diagonal. Serve steak over soba noodle salad, drizzle with remaining 1 tablespoon sesame oil, and garnish with remaining scallions.
