Themes and variations
In a prior thread, I had mentioned my fondness for a variation on the BLT theme: since I cannot abide mayo on sandwiches, a friend introduced me to his family's tradition of substituting peanut butter for the mayo in a BLT. He did this at a greasy spoon in New Hampshire, and the chef at first refused the request, but relented after we insisted.
It was shockingly delicious!
So, with what kinds of deliciously heretical variations would you like to evangelize the chowhound world?
