Place the chicken or shrimp in a bowl and toss with the cajun seasoning until it’s well coated, set aside while you prepare everything else.
In a large skillet over medium high heat melt the butter, add the olive oil once the butter is melted. Add the chicken or shrimp and cook until done about 5-7 minutes.
Reduce heat and add the remaining ingredients except the cheese. Simmer until the cream has thickened, about 5 more minutes.
Just before serving, pour the sauce over the linguini and top with the cheese.
