Blue Cheese Burgers

Mmmmm.  Sometimes I don't like burgers because I find them overwhelming to eat, but this summer I have really been craving and enjoying them.  This is a great recipe, mainly due to the blue cheese, which adds so much flavour.  The recipe is from allrecipes.com:

Instead of chives I used green onion; instead of dry mustard I used dijon seed mustard; and instead of hamburger buns I used an assortment of "odds and ends" bread.  Please note the regular use of the new cast iron pan!
