I love you, McRib
The McRib is a product of “restructured meat technology.”
“Restructured meat products” contain a mixture of tripe, heart, and scalded stomach, which is then mixed with salt and water to extract proteins from the muscle. The proteins bind all the pork trimmings together so that it can be re-molded into any specific shape — in this case, a fake slab of ribs. Mmm, it tastes so good!
