Thanks to curious scientists with time on their hands like Rob Cockerham, of cockeyed.com we can add up the total cost of lunch.
Cockerham took a measured approach to sandwich construction, weighing knife-fuls of mayonnaise and squirts of mustard.
He figured, for example, that an average mustard application is 3.3 grams. Dijon mustard, at $6.99 for a 454-gram bottle, "is to yellow mustard as a Rolls Royce is to your Honda," adding 5 cents to the price of a sandwich.
It's all on the self-explanatory sandwich calculator. A turkey and Swiss on Kirkland multi-grain with mayo and avocado is $1.18, where an American cheese on white is 29 cents.
