If you haven't made a chart for your 3 month (or 2 week, or 6 month; however much you choose to store) supply, now's your chance! I'm making a new one, since I just made a new menu (I feel like I just made a new 3 month supply chart).
So, here is the start of my new 3 month supply chart. All I have done so far is write the meal across the top, and the ingredients required along the side. Then I fill in how much of that ingredient is required to make the meal. Ingredients that are only used in small quantities (like dry mustard) or that are staples (like flour) go in my ingredient list in the second tab.
