My husband really seems like to like his hard boiled eggs this way. I personally don't care for Cajun seasoning, but I make them special for him.
I've also tried them with McCormicks Grinders Italian spices and he liked those as well.

Perk up a plain-Jane hard-boiled egg with zesty Cajun spice blend.
