Stir fry until all ingredients are cooked, about 3 to 4 minutes. Add eggs and toss together until scrambled. Add noodles to the wok. Mix well to combine all ingredients. Pour in reserved sauce. Cook, stirring constantly, until noodles are soft and tender. If they appear dry, add up to 1/4 cup water. Stir in bean sprouts, green onions and peanuts, and fry for one more minute. Taste for seasoning, adding more lime or chili as needed. Serve Pad Thai garnished with coriander, lime wedges, bean sprouts and optional chilies.
