"Create a tasty, well-seasoned Chinese-style chicken noodle recipe that is generally gentle for someone with Crohn's disease who is between flare-up and remission. Keep it low-fiber and easy to digest, avoiding very spicy heat, heavy grease, and hard-to-digest ingredients. Include optional leek if appropriate, but keep it mild and cooked very soft. Use simple, flavorful seasonings such as ginger, garlic-infused oil if suitable, soy sauce, sesame oil in small amounts, and a light broth-based sauce. Make it comforting, balanced, and suitable for a sensitive gut. Provide metric units only."
