The following list is something I pulled from a Betty Crocker Cookbook and it truly is a good list to consider when donating to your local food pantry. (Check to make sure they have refrigerators if you donate items that need to be kept cold).

(Keep in mind that canned foods keep for a year, generally speaking. Do keep in mind expiration dates, even though most foods can be used after the date, some foods can't and it's not fun for a family to get foods that are all expired and spoiled).
