Get Organized: First start in the pantry. Arrange all of your canned/dry goods in categories. Put all tomato based products together, canned veggies, soups, beans, etc.
Start The Inventory: Write down exactly what you have and the quantities of everything in your pantry, freezer, and refrigerator
Start Planning: Once you have your inventory go through some recipe ideas. Take notes.
Make A Shopping List: Create a list for the items needed.
Write Out A Calendar: You can schedule when you will prepare menu items or you can just make a list and cross them off as you prepare them.
