Linguini Mushroom Alfredo

I made this up the other night and it was fabulous. I told mom and dad about it and they asked me to put it on the blog so here we are:

A pound of mixed mushrooms, sliced
2-3 Tbsps butter
1/2 cup marsala wine
1 cup half and half
1 1/2 cups parmesan cheese
1/3 cup chopped, fresh parsley
1 tsp fresh minced garlic
1 box linguini noodles
1-2 green onions

I liked a mix of wild and regular white mushrooms. Portobellos would be great too.
Put butter in a sauce pan over medium heat to melt.
Wash and slice the green onions and mushrooms.
Sautee onions, garlic and mushrooms in butter until they soften.
Remove onions and mushrooms.
Deglaze pan with the marsala wine.
When the wine/butter is simmering, add the  half&half.
Add parmesan cheese.
I whisked in about a tsp of flour to help it thicken.
Once the sauce has thickened put the mushrooms back in and add the fresh parsley.
DON'T LET THE SAUCE THICKEN TOO LONG!

Serve over Linguini that has been boiled 8-10 minutes (al dente)
