It depends on how their packages. My assumption with the couscous is that it's the uncooked grain in a box with a sealed envelope. shrug - it's got an expiration date, but we all do. Just rotate.

As for the pepperoni and salami, that's like any other sausage or jerky - sealed in a vacuum bag and pretty much ageless. Ham, turkey, chicken, beef by the 5 oz or foil pack? I think that's a single serving size and it'll have an expiration a few years off.

The cheese I don't know about. I'm not in to cheese.

I figure those who know would whip up a quick quiche. :->
