Combine ground turkey, diced mushrooms, green onions, 2 teaspoons cornstarch, 1 teaspoon soy sauce, and sesame oil in a bowl, and shape into 16 (1-inch) meatballs. Place meatballs on a single layer of wax paper.
Combine hot water and rice sticks in a bowl, and let stand 15 minutes. Drain well, and snip with scissors twice. Combine 1 teaspoon cornstarch and broth in a large bowl. Add 2 teaspoons soy sauce, sherry, and lime juice. Add rice sticks, sliced mushrooms, ginger, curry, and garlic, and toss well.
Place the noodle mixture in the prepared oven bag. Place the meatballs on noodle mixture, and fold edges of bag over to seal. Bake at 450° for 20 minutes or until the meatballs are done. Place the oven bag on platter, cut open with a sharp knife, and peel back foil. Sprinkle with minced cilantro.
