Check out this video with a few ways to use magnetic dry erase board magnets in your kitchen. I personally use mine to:
Manage my groceries (even though I primarily use grocery gadget),
Manage my weekly meal plan (which I bounce off of my 31 day meal plan…you gotta check this out),
And keep track of when I open perishable items like milk, creamers, cheese, deli meats, etc. so I have an idea of how long an item has been opened and if it’s going to expire or spoil soon.
