As I'm sure we've mentioned before, one of the best parts of a crawfish boil is the inevitable leftovers. There's corn, potatoes, garlic, and of course, crawfish. Now, the potential for super yummy leftover recipes are all but endless but what do you suppose would happen if you took one of the South's most iconic get-together foods (the humble crawfish) and combined it with one its most famous snacks?! The grilled crawfish and pimento cheese sandwich of course! Well, those two things and bread and butter naturally.
