One example was the bone bag - a bag for collecting "vegetable scraps and leftover meat bones in plastic bags and freezing to then utilize the contents by cooking in an Instant Pot with water and apple-cider vinegar and then adding rice and quinoa for a soup base.
Or leftover pizza , chopping it up, crisping and then mixing into scrambled eggs.
A quoted survey looked at "consumers’ leftover habits for 15 years, said 49% of respondents in October reported eating more leftovers than six months ago, a record since the survey began."
This is worth applauding as there is a push to reduce food waste. But for consumers, this is more for reducing their food bill.
From a safety perspective, freezing leftovers prior to spoilage is key if those leftovers cannot be used within a few days.
