Slice the hard boiled eggs in half, remove the yolks and place in the bowl of a food processor (altenatively you can place the egg yolks in a large bowl and use a hand mixer to make the filling).
Add in the grated cheddar cheese, mayonnaise, dijon mustard, salt, pepper,garlic powder and smoked paprika. Mix together (with either a food prcoessor or hand mixer) until smooth. Pour in the pimentos with their juice and pulse until just combined.
Using a piping bag or a spoon fill each egg white half with the yolk mixture. Garnish with chopped dill and chives and serve as desired.
