1. Bring water to a boil in a soup pot. Add green onions, carrots, fish sauce, chili sauce, garlic, ginger, and basil to pot. Add 2 ramen noodle seasoning packets (if you add all 4 packets, the soup will probably be too salty). Boil 5 minutes.
2. Add shrimp, spinach, mushrooms, and ramen noodles. Cook 5 more minutes. Add lime juice and zest. Stir well and serve.
