Carefully peel each hard-boiled egg. Slice them in half lengthwise.
Using a spoon, carefully scoop egg yolks from hard-boiled eggs.
In a small bowl, mix egg yolks, mayonnaise, wasabi, sriracha, half portion of thinly sliced chives, salt, and chili flakes until smooth. You can also use a small food processor or an immersion blender to make it ultra-smooth.
Fill a Ziplock bag with the egg yolk mixture and carefully cut the tip off leaving a 1⁄2 inch hole. Carefully pipe in about 1 tablespoon of filling into each egg white half.
Garnish with bacon bits, the rest of the chives and optional toppings you’d like. Serve immediately!
