here are the things that if you ask me, we all need to have handy. the expiration date on most spices extends over a year, sometimes more. also, most spices don't actually go bad either!
have on hand...ground black pepper
cumin (or chile powder)
oregano (or "Italian Seasoning")
roasted red pepper
if you're a costco member, many of these spices in giant containers are about $4-$6 which can be the total amount of one of the smaller bottles at the grocery store! for things like garlic powder, black pepper, and dried parsley, if you have the space, get the big containers!
