Storage: Store in an airtight container in the fridge for up to 3 days. To reheat, place the salmon in a baking dish and cover with foil. Bake in a preheated 275°F oven for 10-12 minutes or until heated through. You can also reheat the salmon in on the stove by adding it to a non-stick pan with a little bit of water. Cover and heat until warmed through.
