In a mixing bowl whisk together the peanut butter, chili oil, sesame oil, soy sauce, rice vinegar, garlic, ginger and honey.
Whisk in ¼ cup (62.5g) of hot water to thin the sauce. Cover and chill until ready to serve. The peanut sauce can be made up to a week in advance.
For the pork wontons:
In a large mixing bowl, add the pork, green onion, garlic, ginger, soy sauce, sesame oil and rice vinegar. Use your hands to gently combine the mixture.
Working one wrapper at a time, place 1 teaspoon of filling in the center, brush the edges with the egg, and fold the wrapper in half, forming a triangle.
Next, overlap the opposite corners, brushing with egg to seal together. Repeat with the remaining wrappers until all of the pork mixture has been used.
Bring a large pot of salted water to a boil over medium heat. Working in batches, add the wontons and cook, until firm and cooked through, about 5 minutes.
Remove with a slotted spoon and divide among serving bowls.
For assembly:
Gently toss the wontons with the chili oil so they are coated. Top with a spoonful of the peanut sauce and garnish with green onions and sesame seeds.

Notes
Ideally I recommend freezing any leftover wontons before boiling them. Simply freeze on a baking sheet for at least 1 hour, then transfer to a resealable plastic bag until ready to use, for up to 3 months.
