Cook the hard-boiled eggs first. Then, plunge them into ice-cold water.

Peel the eggs and slice them in half. Add the yolks to a bowl and mash. Add the avocado, some cilantro, lime juice, garlic powder, and cayenne pepper. Mash, then season with kosher salt and black pepper.

Pipe or spoon the mixture into the egg white halves. Sprinkle with the reserved chopped cilantro and paprika. Top with slivers of fresh radish, if desired.
