Preheat the oven to 375 degrees F.
Brush a baking sheet and the wonton skins lightly on both sides with 2 teaspoons of oil. Season with salt and bake for 10 to 12 minutes, or until browned and crisp. Transfer to a cooling rack and reserve.
In a large heavy skillet or wok, heat the remaining 1 tablespoon of canola oil over medium-high heat. Add the scallion, garlic, cabbage, celery, bamboo shoots, and mushrooms and stir-fry until cabbage is soft and wilted, about 3 to 4 minutes. Add the sugar, 3/4 cup of the chicken broth, soy sauce, and sesame oil and cook for 3 minutes. Add the sherry-cornstarch mixture and, if the mixture is a little dry, the additional 1/4 cup chicken stock. Add the turkey or chicken and heat through. Serve the chop suey over the cooked brown rice and top with sesame seeds and reserved crushed wonton skins.
Yield: 4 servings (1/2 cup brown rice, 1 cup chop suey, 2 wonton skins)
