It has to meet this 2 requirements:

• It's produced from the waste of another product.
• Its ready to eat.

I think sausages and ham meet this requirement since they are made from trimmings, maybe some cereal brands but i dont know. In México, if you buy a liter of cooked beans made by a small store, it is very likely made from broken beans and bad beans left when grain is processed so i think that also meets the requirements.

Also being honest, probably chicken nuggets are made with trimmings, in spain theyre even called "croquetas" which its the same word for dog and cat food.
