- 1 (1 pound) loaf sourdough bread, cut into cubes
- 1 (8 ounce) bottle honey mustard
- 2 cups shredded Swiss cheese, divided
- 2 cups diced ham, divided
- 1 (6 ounce) jar dill pickle relish, drained
- Spread the bread cubes into a shallow pan and let the bread sit until the cut surfaces are somewhat dried with the insides remaining soft, 2 to 3 hours.
- Preheat oven to 350 degrees F (175 degrees C). Grease a 2-quart baking dish.
- Put bread cubes into a large bowl. Pour honey mustard over the bread and mix to coat. Layer about half the bread cubes into the bottom of the prepared baking dish. Sprinkle 2/3 cup Swiss cheese over the bread cubes; top with 1 cup ham. Spread relish in a layer over everything. Layer remaining ham, 2/3 cup Swiss cheese, and remaining bread cubes, respectively, atop the relish layer. Finish by topping with the remaining Swiss cheese. Cover entire dish with aluminum foil.
- Bake in preheated oven until hot in the center, about 30 minutes. Let cool 5 minutes before cutting to serve.
