Make the dressing: In the bowl of a food processor or in a blender, combine the soy sauce, vinegar, sesame oil, mustard, honey, sesame paste or tahini, ginger, and chili oil. Pulse several times to combine, then, with the motor running, slowly add the peanut oil and process until the dressing is emulsified. Taste, and season with salt, pepper and/or more chili oil, if needed. You should get about 1 cup.
Step 2
Make the salad: In a large bowl, toss together the green and red cabbages, lettuce, onion, carrot and half of the wonton strips until well distributed. Add half of the dressing and toss until well coated. Add half of the orange pieces and half of the cashews and toss lightly to combine.
Step 3
Divide the salad among 4 plates and garnish each portion with the remaining wonton strips, oranges and cashews, and the sesame seeds, if using. Serve with the remaining dressing on the side, if desired.
