Used to think those fridges with the glass in the door were stupid… until I realized if I can’t see into my fridge from the outside I forget what I have in there
I keep a dry erase board on my fridge and when I get back with groceries I write down what I got (usually list of meals, list of veggies, etc.) and cross off or erase it as I use them. It helps me out a lot with this issue!
