In a medium bowl, mix together the scallions, ginger, 1/4 cup of the
oil, 1 1/2 teaspoons of the soy sauce, vinegar, and salt. Cover the tofu
with the remaining soy sauce and set aside. Allow to sit at room
temperature for 15 minutes.
Bring a large pot of water to a boil. Heat remaining 2 tablespoons
oil in a 12-inch skillet over medium until shimmering. Add the tofu and
cook until golden, about 4 minutes total, turning the pieces once.
Transfer tofu to a paper towel-lined plate, then cook noodles according
to package directions.
Drain the noodles and toss them with the ginger scallion sauce in a
large bowl. Transfer to individual bowls and top with the tofu.
