I have about 80-100 pounds of various grains and beans sealed up in mylar bags with oxygen eaters in large restaurant buckets.
I also have a reasonable supply of canned food, dehydrated food, and various spices.
A good (ie: cheap) way to cook grains and legumes is to get a soup-sized, wide-mouth Thermos. Make sure that it's an actual Thermos brand. You fill the thermos 1/4 to 1/3 of the way with a mix of different beans and grains, pour in boiling water, and seal up the thermos and let it sit for a few hours.
The grains and beans will be perfectly cooked.
The reason why we mix grains and different kinds of beans together is to "complement" the proteins.
The body cannot process protien unless all of the essential amino acids are present at the same time.
There are, for example, 9 essential amino acids out of 21 total amino acids. If you eat a protein that has 8 essential amino acids in huge abundence, your body won't utilize any of this protein at all because the one essential amino acid is missing.
With a mix of different beans and grains, two different plant protiens may each be missing a different essential amino acid, so the two together give you a complete protien.
A good example would be kidney beans, pinto beans, and soy beans cooked together with brown rice and eaten at the same time.
Storing huge amounts of beans and grains is very cost-effective. Maybe $190.00 might get you enough food for over a year.
Just include spices and mixes for sauce so that this dietary monotony won't make you crazy.
Also, store honey in a cool, dry, dark place. Honey is not only a sweetener, but it helps heal wounds and burns, and it can be mixed with water and fermented into a strong alcoholic drink called meade. It can also be used for trade purposes.
And remember--honey--if stored properly--can last for well over 20 years without refrigeration.
Just make sure you never give honey to any kid under the age of 6. A kid under 6 years of age can get a kind of gastrointestinal botulism, and possibly die from it.
A possible exception is if the kid has diabetes. If honey is all that's available during a blood sugar crisis, then I would suggest using it if that's all you have.
