Boil the eggs for 10 minutes until hard-boiled. Transfer them immediately to an ice bath to cool, then peel carefully.
Slice the eggs in half lengthwise and remove the yolks, placing them into a bowl.
Mash the yolks with mayo, chili crunch, salt, and pepper until smooth and creamy. Adjust seasoning to taste.
Transfer the yolk mixture to a small zip-top bag and cut off one corner to create a piping bag.
Pipe the filling evenly into the egg white halves. Optionally garnish with sesame seeds, more chili crunch, and parsley.
