1.) Cook Linguine according to package instructions until al dente.  Cool under running water and lightly oil.

2.) Heat a heavy pan (large enough to hold the linguine) over medium heat.  Melt Butter in the Pan.  Add the Andouille sausage and sauté until it begins to brown.

3.) Add the crawfish meat and Cajun Blackening Seasoning.  Cook for one minute.

4.) Add the half & half.   Bring to a boil.  Add the linguine and toss together until well coated and thoroughly heated.

5.) Sprinkle in half of the parmesan cheese and toss thoroughly.

6.) Portion onto warm plates and garnish each plate with the remaining parmesan cheese and green onions.

Note:  Cajun Blackening seasonings vary in heat and intensity.  Adjust the seasoning to the desired spiciness...  This is a spicy dish.  Add the spice slowly, you can always add but you can't take it out.
