I'm lucky I don't ever have to use canned salmon, so I use grilled fresh salmon leftovers for this great sandwich. My recipe source here is the Alaska Seafood Marketing Institute who acknowledged Edwina Gadsby of Great Falls, Montana. This recipe was 1 of 6 winners of the "LUV SALMON SO MUCH" recipe contest & it's a winner in my book too. This makes a very good brunch or luncheon item, but is also esp good for TO GO occasions because of its easy portability & the fact the sandwinches can be made up to 6 hrs in advance. Enjoy!
