Nutella on butter flavored popcorn. It is so freaking good. Just get a glob on a butter knife and dip into popcorn, eat and enjoy. Popcorn is also really good if you eat it with snickers or milky way candy bars (when I did this I'd just get one or two of the snack size ones). Now I have discovered a love of frozen sugar free Reese's cup minis.
I am one who loves peanut butter and pickles (preferably bread and butter, though spicy garlic ones are pretty awesome as well).
For a while I would crave iceberg lettuce or sliced tomatoes with copious amounts of salt. None of which I actually like all that well (turned out to be a form of pica due to severe iron deficiency anemia).
