Salmon sandwiches

A PRODUCT OF HER TIME, as who of us is not, Lindsey still clips recipes from here and there. I saw the recipe for this salmon sandwich the other day on our kitchen island, but I didn't pay enough attention to it — I never pay enough attention to anything — so I can tell you neither whence it came nor what it stipulated.
In any case it involved poached salmon and onions, I know that from washing the dishes; and mayonnaise, and cilantro, and one or two other things. The sandwiches were on ciabatta rolls from The Bakery (in our family that means Healdsburg's Downtown Bakery and Creamery). And they were accompanied by green salad with butter lettuce and sliced tomatoes, and preceded by almonds, and followed by apple crisp; and while we ate them we watched the presidential debate, lordy me.
