Sam-gyeop-sal, is a staple pork dish in Korea.
Sam (삼) means "three"
Gyeop (겹) means "layers"
Sal (살) means "flesh"
So, sam gyeop sal actually means, "three layers of flesh". In English, it is usually called "fresh side," which is basically just thickly sliced, uncured bacon. So it's not the most healthy food in the Korean diet, but it is one of the most delicious. It's generally cooked on a grill in the center of the table, and eaten with lettuce, red pepper paste, kimchi, garlic, and wide variety of other side dishes.
