For the dressing: In a medium bowl, combine the peanut butter, rice vinegar, sesame oil, lime juice, soy sauce, canola oil, sugar and honey and whisk until smooth. Add the red pepper flakes, garlic, ginger, cilantro, and sesame seeds and mix until combined. Alternately, you can combine all ingredients in a blender and process until completely smooth. Let dressing rest for 10 minutes before tossing with salad.
