I won't try to write out a recipe for my Grilled Cheese and Salted Watermelon (with greens), because I'm sure you can guess how I made it. What I will do though, is share some tips: if you don't have a sandwich press, cast iron is great for grilling bread. Put some pressure on your sandwich, though. My brilliant system today involved a plate and a full kettle. You could use a plate and a nineteenth century novel. Whatever works...
P.S. I tried to be really discreet about my use of Challah in making the grilled cheese of this post. I though you're so sick of this loaf of bread by now. But then I got a comment on the last post from Amuse- bouche that sent me back to the kitchen. I came back with this tiny grilled chocolate sandwich to have with my espresso. And that, ladies and gentlemen, is the sweet sweet conclusion to my lovely loaf of Challah.
