The best resource for food, for most people, is the grocery store. Expand your pantry to cover three honest day's worth of food for you and your family. Purchase things that you eat on a regular basis, and rotate your stock. Improve your cooking skills with shelf stable foods and slowly expand, without going into debt, your pantry.
This is part of our pantry (which needs a organizational overhaul) and how we save money at the grocery store. When products that we use go on sale, we stock up our pantry. For example, the two cases of canned organic pumpkin was on clearance after Thanksgiving for about 75 cents a can. It's usually $1.67.
I have a fairly good memory and can spot excellent deals. The top left holds our pasta, that is currently very low, but it goes on sale for .39 a pound once or twice per year. When it goes on sale, I'll probably buy about 60 pounds between three stores, since we have spaghetti night at least once per week for the five of us.
I've tracked food prices with a notebook (LINK), my phone, and on the item itself (with a sharpie) to stretch the most from our food budget.
Gradually increase the pantry's supply to feed your family longer and longer periods of time. Don't forget a manual can opener.
