i personally have found that buying fresh veggies is a real waste
they almost guaranteed to go bad before the end of the week or we dont use up all before we go to buy more groceries.
So i have cut down drastically on the fresh veggies.
Move to pre packaged frozen veggies and canned stuff and just keep inventory.
If your fridge is constantly to packed to hold all the perishable food your buying, definitely a sign that your wasting food.
we freeze alot of food, but thats also a meh-ish point since if the freezer always full, then it means we not consuming that food we freezing.
So maybe buy food this week, make meals, freeze meals, then dont buy the next week, use up all the frozen food, then start over.
