I am finally getting around to posting my 3 month supply examples. Sorry it has taken me so long.
One method for developing a 3 month supply is to use what I call the pantry method. What's in your cupboard, fridge and freezer? Store more of that. Examples can be seen here, and here.
You can find a wonderful example of the very organized approach (what I explain in my 3 month supply posts) here (under Helpful Tools).
I do a combination of the two methods. Here is my example. Sheet 1 is the Very Organized Approach (it's organized to me--I hope it makes sense to you), and Sheet 2 is the Pantry Method. Please keep in mind that this is my worksheet and it changes regularly. I only make changes on what I have and need when there is a great sale on the item and I plan to purchase some. No, my family does not only eat meals with cheese. The list of meals is just an example of some of my family's favorites. This list provides ingredients that my family uses the most, allowing me to usually have more than enough for me to make any meal I choose.
