pretty much any of it except those vile soft german sausages and tongue. tongue's just bloody disgusting, even if you're not appalled by where it comes from - there's something metallic and urinous and orrid in the taste, bit like liver taken to unpleasant extremes. I really like fennelly or peppery coarse-cut salami but the more minced-up ones tend to the extremely greasy.
finest for me are san daniele ham (sweeter and softer than parma), bresaola, really good pata negra, chorizo, pastrami esp with lots of spicing, cold roast beef but only if it's rare, cold roast pork leg that's been roasted with lemon and cumin ... they're all bloody good but horribly expensive. to repeat, pretty much anything except german sausage or TONGUE *retch*
