Ingredients
Mayonnaise and plum or tomato jam, for spreading
4 slices white sandwich bread
2 large romaine or other crisp lettuce leaves, torn into pieces
8 ounces thinly sliced roast turkey
2 ounces thinly sliced aged Gouda
2 slices whole-wheat or multigrain bread
2 thick slices beefsteak or heirloom tomato
Kosher salt and freshly ground pepper
4 slices bacon, halved, cooked until crisp, and drained on paper towels
Preparation
Spread a thin layer of mayonnaise over one side of each white-bread slice. Heat a skillet (preferably cast iron) over medium-high; add white bread, mayo-sides down, and reduce heat to medium-low.
Cook, undisturbed, until a crisp, golden-brown crust forms, about 2 minutes. Transfer bread to a cutting board or plate, toasted-sides down.
Spread a thin layer of jam over untoasted sides of 2 white-bread slices; divide half of lettuce, half of turkey, and all of cheese evenly on top. Spread a thin layer of jam over one side of each wheat-bread slice and place on top. Stack remaining turkey on wheat-bread slices.
Top with tomato, season with salt and pepper, then top with bacon and remaining lettuce; sandwich with remaining 2 white-bread slices, toasted-sides up. Serve immediately.
