Slice peeled eggs in half lengthwise.
Gently remove yolks and place in a bowl. Add mayonnaise, dijon, and relish. Mash until smooth.
Stir in dried or fresh dill, salt, and pepper.
Place the filling in a piping bag or a Ziploc with a piping tip, and pipe carefully into the egg white halves. You can also scoop the filling into the egg with a spoon.
Garnish with thinly sliced jalapeños and refrigerate until you’re ready to serve.
