Liverwurst/Braunschweiger
White bread
Yellow mustard
Hard bagged pretzels (fresh hot pretzels are another thing entirely)
Orange soda
Fig Newtons
Aw, man. These are all beyond “meh” and well into “bleh” in my book. 
It’s roast beef for me–I’ve never liked it but every few years I decide I’ve just never had it prepared right, and try to make a good one. Bleh.
