Start by making the sauce. Combine all sauce ingredients into a bowl and set aside. Be sure to stir again just before using.

Prepare the wraps now. Heat the 2 tablespoons of canola oil over high heat on a skillet. Add chicken and stir fry until it is cooked, about 3 minutes. Add celery, carrot, peas, bell peppers, and red onions. Stir fry for about 3 more minutes. Now add the garlic, ginger, sprouts, and shiitakes. Take the prepared sauce, and add 1/4 a cup of it and until thickened, about 30 seconds. Scrape any brown bits. Transfer this stir fry to a bowl and top with scallions and peanuts.

Wipe off the skilled before heating the remaining 4 tablespoons of canola oil over high heat. Fry your wontons until crisp and golden, which is about 15 minutes per side. Place on paper towels and season with salt to your liking.

Take lettuce and fill the leaves with the stir fry. Take the sesame seeds and sprinkle on top. Crumble your wontons on top or serve on the side. Serve now with remaining sauce.
