I got this idea from my future mother-in-law. She bought some of these to try after a woman she knows said she sent these to her son in Iraq during the winter. They actually taste great! They come in many flavors like hot chocolate, coffee, and cappuccino. They have the directions printed on them and you just pop a tab on the bottom, let them heat up (about 3 minutes), and drink! They get REALLY hot, so if you buy one to try be careful! I've seen these for sale at Wal-Mart.
Happy Care Packaging!
