Cook soba noodles according to package directions. Drain and set aside.
Heat canola oil in a large skillet over medium heat. Add cubed tofu and sprinkle with salt and pepper. Sear until golden brown on each side.
In a large bowl, toss together the noodles, cucumber, carrots, cabbage, cilantro, and Bang Bang Sesame sauce until all ingredients are evenly coated in the sauce.
Divide into four serving bowls, and top with seared tofu. Serve warm or chilled.
