Cut the hard boiled eggs in half lengthwise. Over a medium mixing bowl, gently squeeze the center of the eggs so the yolk pops into the bowl. With a fork, mash the yolks with the mayo and mustard until smooth. Add the lime juice, siracha, and salt, and mix until incorporated. Taste for seasoning.
Using a teaspoon, carefully scoop the filling into the cavity of each egg. Arrange on a serving platter or cutting board, garnish with a shake of paprika and half a lime, and enjoy!
