Cheeses mostly don't taste salty, but many of them are (usually the harder the cheese, the more sodium content), and I don't know about jalapeño jack.

Skim and non-fat milk and yoghurt are somewhat higher in salt content than whole milk. If you do dairy, that is.

Sushi and seafood generally. Although there the salt is a feature... Hmmmmm... Cookies and cakes have a lot of sodium (both salt and leavening) but the sweetness covers it.
