I just bought some salmon with only the heart of the filet, no side and the tail thing.
It was more expensive ok, 23€ the kilo, but god, how good it was!
Its like a relief for my body, my body thanking me for it.
I decided not to buy cheaper salmon anymore. I prefer to wait a day or two
to buy better quality. Our body can hold on a few days without omega3 i guess.
