Plan ahead these need to chill for 3 hours before serving, these are really good! Make certain that eggs are completely cooled before slicing in half and butter is very soft but not melted, you can adjust all ingredients to taste
Slice the peeled eggs in half lengthwise; carefully remove the yolks and place into a bowl.
Add in soft butter, mayonnaise, Dijon, lemon juice and green onion, cayenne pepper, 1/3 cup finely grated cheddar cheese and 1 teaspoon seasoned salt; mix very well until smooth, then season with pepper to taste.
Spoon or pipe the mixture evenly between the egg white halves.
Place a small amount of shredded cheddar on top of each egg (you can use more than 1/3 cup if desired for the tops of the eggs).
