I like to plan my food for the week and do my grocery shopping on Sundays. Typically through the week I jot down meal ideas in my notes app on my phone. Once I have five or so meals put down I work on filling in the ingredients and determining what I have on hand and what I need to purchase. Ingredients are then grouped together and broken out by store. I like to go to trader joes for fruits, yogurts, nut butters, and all natural sauces and Vons for the rest. I typically only buy fresh meat for the first 2 days of meals and then pick up meat on my way home through the week to make sure it’s as fresh as possible.
For daily meal planning, I use the notes application on my phone and write down the number of 21 day fix containers I get for the day and the contents of the container broken down by ingredient. I then update my list nightly for the next day to make sure I stay on track.
