Choosing how to approach your three-month supply is highly personal. I've waffled back and forth with several methods and have finally settled on the one that I think will work best for our family. But just because it is best for us, doesn't mean that you have to approach things the same way. The sub-goals that I'll be using can be applied to most of the following methods of gathering your three-month supply. Continue to follow along, but feel free to use your own approach. The goals should help you regardless.
Here are some different methods of tracking/collecting a three-month supply:
Create a menu for breakfast. Buy 93 days worth. Then work on lunch and finish with a dinner menu. (This is the method that I'm using. I'm choosing to use this method because it allows me to work with smaller menus, yet still buy items in bulk.)
Create a 7-day menu for breakfast, lunch and dinner. Work on getting one-week's worth of food. Continue acquiring food in weekly chunks until you have 14 weeks of food.
Create a 31-day menu. Multiply by three for three-months worth. Shop sales to acquire your food supply.
Three Month Menu
Figure out your entire menu for three months. Shop for ingredients in bulk.
Make two separate menus for breakfast and dinner. Double the amount for dinners and count the double towards lunches. This is the method that my sister uses. She doesn't want to keep track of separate menus for lunch and dinner.
Live entirely off foods you have in your pantry for one week (or one month). Keep a detailed list of everything you use. Use that list as a weekly/monthly menu and shop accordingly.
What method do you use? Please post your approach and I'll either add it to this page or devote a post to your ideas!
