Some of my favorite sandwiches need very little prep work, just the right combination of top-notch ingredients. This is one of them. Dark bread, smoky fish, tart apple, and complex Gouda make magic together. All you have to do is slice, spread, cut, eat, and smile.

Ingredients

　　2 slices pumpernickel bread

　　2 ounces smoked trout, flaked with a fork

　　1 ounce aged Gouda cheese, cut into thin slices or crumbled

　　1/2 small to medium Granny Smith apple, cored and cut into 1/4-inch slices

　　A few leaves baby arugula or baby spinach

　　Freshly ground black pepper

　　To assemble the sandwich, spread the mayonnaise on one side of both pieces of bread. Mound the trout on one of the bread slices, then top with the Gouda, the apple, and the arugula. Season with pepper. Top with the other slice of bread, cut in half, and eat.
