My daughter says this way is best:

slather a large tortilla with peanut butter (creamy)
pop in mocrowave oven for 20 seconds or so
fold over and eat while tortilla is soft and warm and peanut butter is hot and drippy
lick the excess peanut butter off your arms

She also says she would definitely advise against peanut butter/salami combination.

C.H., I'm not sure if I could chew my way through a whole peanut butter and marshmallow fluff sandwich these days, but as a child I thought they were magnificent. My other favorite, also taught to me by my grandmother, was white bread slathered with butter and white sugar, which would probably send me into some sort of glycemic shock nowadays, not to mention make my teeth ache. Didn't you ever love anything as a child that you wouldn't like now?
