In a bowl, combine marinade ingredients and marinate scallops while you prep the rest of the ingredients.
Cook soba according to package directions; drain. In a large mixing bowl, combine soba with remaining pasta mixture ingredients. Toss like a Caesar salad.
In a skillet, heat oil over medium heat and saute scallops 1 1/2 minutes on each side; do not overcook. Pour scallops and juices right over soba.
