Reasonably nutritious - possibly looking at months. We have a huge bag of rice, large bag of pasta, and sizeable bags of various beans and lentils, as well as oats, barley, nuts (H buys in bulk from Grape Tree), couple of jars each of peanut butter, Marmite and tahini. Frozen peas and pickles (beetroot, cabbage, onions, cornichons, 2 sorts of olive) enough for a couple of weeks, pile of tomatoes and a large butternut squash waiting to go in the freezer, some jam and marmalade, about 10 litre cartons of orange juice and 6 of beetroot juice.
Edit - oh, and the raisins, apricots and prunes, couple of kg bags of each
I'm not sure what meat is in the freezer - don't think we've got the turkey yet. Possibly a couple of guinea fowl and a leg of lamb. Maybe even two. Tins of tuna, corned beef and mackerel, enough for about 12 meals for 2.
There's also a lot of wine and beer (H makes it from kit) which isn't entirely empty calories ;-)
