Lunch meat and crackers stored in the same bag is going make the crackers soggy, even if they don’t touch. There’s enough moisture in a slice of bread to make crackers or chips stale if stored together for a few hours.
Lunch meat touching the bread is going to sogify the bread.
Bread stored in the fridge accelerates the staling process - it’s actually fastest at about 40F
My son reports that an unwrapped sandwich placed in a plastic container at 7am will make potato chips in the same container to be stale by lunchtime. Storing this stuff in the fridge for an extra 12 hours is going to make things worse. If you’re going to do something like this, you need a waterproof/fat barrier (e.g. bread-cheese-meat-mayo-bread or putting peanut butter on both halves of the sandwich before adding jelly) in the sandwich and need to keep the sandwich separate from any chips/crackers/pretzels.
My kids sandwiches constructed with fat barriers and placed in ziplock bags which go in plastic containers along with chips, pretzels, fruit or whatever else. The kids are instructed to bring home the ziplocks which get re-used.
I was coming here to say that, and leaving bread wrapped in paper in the fridge for days isn’t going to do that sandwich any favors either. I get the impression whoever made this video solved for ‘visually compelling’ at all costs.
That’s just too much plastic packaging going straight into the landfill. It’s a small investment to buy reusable plastic containers. So much processed food! I have a kid and I hated making lunch for her because she was such a picky eater. She wouldn’t have eaten any of this.
Leftovers people! Leftovers. Spaghetti tonight is lunch tomorrow! Easy peasy.
