In a blender, combine sesame oil, peanut butter, soy sauce, rice wine, water, rice vinegar, canola oil, brown sugar, ginger and chili garlic sauce. Blend until smooth.
The sandwiches:
In a large bowl, stir together the chicken, red bell pepper and carrot. Add about two-thirds of the peanut sauce and toss to coat. Add more to taste, if desired.
Divide the chicken mixture and romaine lettuce evenly between the pita halves. Drizzle with extra sauce, if desired. Serve.
