This recipe started out as a Costco recipe, but I didn't have all the ingredients at the time and had to improvise. The trick is to make sure you don't over cook the salmon, so check it after 15 minutes. With thicker fillets, it'll probably take a little longer, but check frequently after 15 minutes. The salmon will continue cooking after you take it out of the oven. You can use as much or as little salmon as you want, and adjust the time accordingly.
