I would not serve meat in any form if it goes in the bin. Animals were not reared and slaughtered to be thrown in the rubbish. Norah’s suggestion sounds excellent and avoids too much waste - left over toast will be enjoyed by the birds.
Left over toast, even buttered or spread with cream cheese, can also be cut up in small dice and frozen for breakfast casseroles.
We use leftover cubed breads often, transformed into this-that.
Certainly never meat waste, as GSM said - not why animals are raised.
