In a large bowl, combine the cabbages, green beans, red bell pepper, pickled ginger, and cilantro. Cover and refrigerate.
In a small saucepan heat the canola oil to 325 degrees F and carefully fry the wonton strips for 3 to 4 seconds, until golden brown. Using a slotted spoon, transfer the strips to a paper towel to drain. Set aside.
For the dressing:
In a blender or food processor, blend together the ginger, green onion, garlic, and cilantro.
For the Tuna:
Coat the tuna with the oil and season with the salt and pepper. On a plate scatter the sesame seeds and press the tuna into the seeds on both sides, gently shaking off the excess.
Heat a large grill or saute pan over high heat and sear the tuna for 3 minutes on each side. Remove the fish from the pan and let rest for several minutes before slicing. The tuna will be medium-rare.
Toss the vegetables with half of the dressing and mix well. Add half of the wonton strips and gently combine. Mound the slaw onto a platter or indivisual plates. Place the sliced tuna on top of the salad and drizzle the remaining dressing on top. Garnish with the remaining wonton strips.
