"The Smokehouse Melt" is a robust, layered sandwich that brings together bold, earthy flavors and a variety of textures. It starts with a thick square of toasted focaccia, layered with a sharp horseradish cream and seared slabs of thick-sliced lamb pastrami that have been browned in butter and fresh thyme. The sandwich is then piled high with savory, black-pepper seared cremini mushrooms and topped with molten, bubbled Gruyère or Fontina. Finished with a nest of crispy onion strings for an extra layer of crunch, this melt is a hearty and sophisticated choice for any meal.
