So I got back from taking my daughter to school this morning to find that my partner had left the freezer open and it'd been open since yesterday tea time.

So now that I've cleaned the freezer and got rid of some things (including a manky bag of sprouts from xmas) I need to restock.
I always like to have in peas, cod for my fussy eater daughter, cook from frozen sausages for my son (he'll turn into a sausage one day I'm sure), and for some reason puff pastry which I hardly ever use but always have in . . .
What are your freezer essentials?
