1) Fish sauce or soy is really good to give food more flavor and don't add many calories either.
2) Use a non-stick pan to cook salmon and other fatty fish. You don't need to add any oil, lots will come out of it when it's cooking and make sure that it doesn't stick. That way no extra fat is added and you even get rid of some during the cooking process.
