connie, i think I wrap it in foil with a little of the poaching liquid and heat it for a few minutes in an oven. You could microwave it, but I'm not a fan of MW's so I'd do the oven, not long just heat it through.. kadesma
Fresh salmon is one of our favorites, and I have found slowly heating leftovers in a double boiler warms the salmon, and does not cook it anymore. I am sure it is too late now, but maybe next time...
