Preheat the grill. In a large mixing bowl, toss the mushrooms with 1/4 cup of the oil. Season with Creole seasoning. Place the mushrooms in a grill basket. Place on the grill and cook for about 2 to 3 minutes on each side, or until the mushrooms are wilted. Remove and cool completely, set aside. Bring a pot of salted water to a boil. In a large saute pan, over medium heat, add the remaining 1 tablespoon of oil. When the oil is hot add the Tasso and saute for 1 minute. Add the mushrooms and continue to saute for 2 minutes. Add the shallots and garlic and season with Creole seasoning. Stir in the green onions. Add the cream and butter and bring the liquid to a boil. Reduce to a simmer and cook for about 6 minutes or until the sauce coats the back of a spoon. Season with Creole seasoning. Cook the pasta in the boiling water for about 3 to 4 minutes or until cooked al dente. Season the pasta with salt and pepper. Add the pasta and cheese to the sauce. Toss well. Mound the pasta in the center of 4 plates. Garnish with parsley.
Combine all ingredients thoroughly and store in an airtight jar or container.
Yield: about 2/3 cup
