We came up with a plan awhile back about dating every food item we open and then seeing how long it lasts. We always do it on certain items like lunch meat or jarred spaghetti sauce in the fridge but this is just on everything in general. It's not really accurate since we never eat the same way all the time but gives us a bit of an idea how long it took us to scarf it down and it's a bit fun to see the trends.
Dave bought this loaf of bread last night around 9 pm. This morning I opened it for breakfast. By lunch I barely had enough for grilled cheese sandwiches. The 2 pieces of crust are left for Daddy since that's his favorite part. I'd say we need more than 1 loaf of bread per week.
