What is this food "cr of leek and pot 21814"?
Google suggested it's a CReam OF LEEK and POTato soup. 

Just follow the instructions on the package to cook this dish. Apparently it is only half-way cooked. Empty the tray into a pot, add as much water as the tray holds to the pot. Heat the soup until it boils, stir frequently. Then, reduce the heat and let it simmer. The package says something with 100°F (?), I can't read it. 

If the package is still frozen, you can leave it frozen in the freezer; otherwise you can leave this package up to 5 days at 40°F in the refrigerator prior cooking (as the package says).
