In a medium saucepan, bring stock and chili-garlic sauce to a simmer over medium. In a small bowl, mix turkey, ginger, 1/2 tsp. sesame oil and 1 tbsp. scallions. Divide among wonton wrappers; fold according to package directions. Add to stock; simmer until turkey is cooked through, about 5 minutes. Garnish with remaining 3 tbsp. scallions; drizzle with remaining 1/2 tsp. oil.
