I had this for lunch. We all need good protein and fish would be the best source of it. In Korea, salmon is easily found but it is not something that Korean people would cook on a regular basis though it is getting more popular each year.
When eating greasy food like salmon, each culture has different ways of making it even. Kimchi, I believe, is the best side dish you can have with because it feels refreshing, spicy and cold. It is like soda pop when you eat burgers. Soda is necessary!
