This no-cook tartine is an ideal light lunch or dinner for one, but we also like to work it into our brunch rotation when the occasion calls for an easy, yet impressive menu. This recipe calls for only a few ingredients, so we like to use the best quality ones we can find: freshly-baked bread, salted European-style butter, marbled smoked salmon, and our artisanal Dill Pickle Mustard. The tangy, dill-scented mustard delivers so much flavor here and cuts nicely through the richness of the fish.
2 Tablespoons salted butter
One ½-inch thick slice rustic bread, such as rye or sourdough
Thinly sliced English cucumber
Kosher salt and pepper
2 to 4 ounces smoked salmon
Thinly sliced red onion and fresh dill, for garnish
