No, it's time to learn how to garden and do it. I started learning last year and now there is food growing in my container garden - grew most of it from seed. I'll have most of the foods listed in that article as being expensive.
You can have your own food and not depend on California to get water from the feds - how likely is California to get water??
Cocoa: Buy cocoa powder, not a mix, and store it (it's either with chocolate drinks or in the baking section of grocery). Doesn't take much powder to make hot chocolate. Here's a simple way to make hot chocolate:
Hot chocolate made using unsweetened cocoa powder
1 tbsp. cocoa powder
2/3 cup of water
1/3 cup of milk (skim or other)
Sugar, other sweetener to your liking (or no sweetener)
Heat cocoa with water almost to boiling point, add milk and sweetener.
