Does anyone have a good, homemade Cajun seasoning recipe?

My husband asked me to ask this, so I’m not sure exactly what he had in mind. I’m thinking perhaps he wants some sort of “seasoning” like dried, crushed herbs that you would shake out on food, like a salt or pepper.
However, I’m sure he would welcome ALL unique Cajun recipes. Also, please rate them on a 1 to 10 scale of hot, with 10 being the hottest. (I prefer 1 and 2, definitely less than 5 because anything more than that simply blows whatever taste there might be to smithereens, and all you get is a macho bonfire in your mouth…IMO)
