For The guys that have I had the pleasure of sharing a boat with and like my sandwich’s.
Recipe: Open and drain water from tuna cans. Use the lid to squeeze as much water as possible out of the can. Add a few drops of liquid smoke to each can and let stand. Chop about a 1/8 of an average size onion (adjust to taste). In a mixing bowl add the onion, 1 or 2 table spoons of sweet pickle relish and the tuna. Start with 4 tablespoons of Miracle Whip Light and a squeeze of horseradish spread. Blend ingredients with a fork and add more Miracle Whip if the batch is to dry. Taste and adjust horseradish to taste. Refrigerate overnight to allow the flavors blend. Serve on your favorite bread or bun.
