Bring a pot of water to a boil and gently add the eggs. Boil for 7 minutes for a jammy center.
Transfer the eggs to an ice bath and let them cool completely.
Lightly crack and peel the eggs.
In an airtight container, combine soy sauce, water, green onions, Thai chili peppers, honey, rice vinegar, garlic, sesame seeds, and chili oil. Mix well.
Add the peeled eggs, making sure they are fully submerged in the marinade.
Cover and refrigerate for at least 5 hours, or overnight for deeper flavor.
