crawfish fettuccine

This is a classic around these parts. It's in almost every restaurant you go to. Back in the day, when I didn't know much about food, but knew you couldn't mess up pasta (or so I thought at the time, wink wink)- this is what I would always get. 
I love spice and love pasta.  This dish brings both to the plate. Don't be scared of crawfish if you haven't tried them! Just be sure to buy the ones that aren't imported.
