pimento are just roast peppers (spear "bell" (sweet)pepper, roast over open flame (gas burner on stove will do) till black, place in a enclosed space (brown paper bag) to lightly steam, peal off skin.) that have been very lightly pickled-- your classic pickled peppers..

they are common enough in NY- $0.25 extra at blimpies to have some on your sandwich.. never understood why they got packed into pitted olives,tho..
