Very enjoyable writing, though I must admit I never understood putting crisps in your sandwiches.
Two lightly toasted slices of NOT white bread, lightly apply very good mayo 1/8 lb of good smoked ham sliced very thin 1 large dill pickle sliced fairly thin
...aaannnnddd a bunch of ruffles potato chips.
Assemble a thin layer of ham, then pile the pickle slices in a second layer, add another ham layer, then pile the chips as the next layer, and add a final thin ham layer to insulate the chips from the top bread slice mayo layer
Eat quickly. Probably need two hands. Likely need to stop walking. There will be crunching noises. I'm not ashamed to admit I've been addicted for 50 years.
