First, I realize someone asked whether they can use a waffle iron. Great question, great idea. Alas, while I do have a waffle iron, it's not a very good one and won't fit sandwiches of substantial thickness.
I do have two cast iron pans. But the smaller one would still crush the sandwich. (I was thinking maybe I could fashion it in the oven somehow) I also have two Calphalon griddles, one flat and one with raised grilling "speedbumps". I also have a variety of other pans, but I think something from among these four would hold the solution.
Just wondering if anyone is using a brilliant alternative to waffle makers or uncheap panini presses.
