Agreed. I would prefer not to, but a 20 pound sack of rice will provide 5 days of cheap calories for a family of four. Throw in some Spam, sauces, and canned veggies, and you've got an adequate emergency food supply for ten days. Repeat as necessary, substituting pasta, flour, corn meal, potato flakes, or other cheap starches for the rice, but still including a variety of supplemental foods. Add some seeds and a garden, and a way of harvesting small game for fresh meat, and it's sustainable.
I have alot of egg noodles in storage, along with those dried gravy packs.
Cook the noodles and gravy, toss in whatever veggies/cheese/meats you have, spice it up a bit, you can eat pretty well!
I never was a very big rice fan, but I have some of that too.
