What does "cajun" mean? I think I've seen the word on the Popeyes menu; Is it a type of spice?

"Cajun" in this scenario is a type of seasoning. "Cajun" is usually made of paprika, cayenne pepper, garlic powder, onion powder, black pepper, crushed red pepper, thyme, and oregano. Cajun seasoning is on the spicier side and seems to be popular in Louisiana cooking. Not only is "Cajun" a seasoning, but it's also an ethnic group that mainly resides in Louisiana! Ex: I want to try making Cajun shrimp pasta. Ex: We are growing Cajun belle peppers, and boy, are they spicy!
