If you love any sort of Italian fare, then canned tomatoes and canned tomato sauce are a pantry must. Canned versions are much cheaper than most jarred products and they're the basis for any authentic red pasta or pizza sauce. They're also great bases for soups and salsas along with many other recipes. And the fact that they're full of disease-fighting antioxidants just sweetens the pot. Fresh tomatoes are usually reserved for dishes like tomato pie, but drained whole canned tomatoes will always do in an out-of-season pinch.
