- 1 tablespoon vegetable oil
- 1 small head Savoy cabbage, cored and sliced (about 7 cups)
- 1 teaspoon caraway seeds (optional)
- Salt and pepper
- 1/2 cup chicken stock, divided
- 2 tablespoons butter
- 2 large onions, thinly sliced
- 1 bay leaf
- 3 tablespoons sweet red pepper relish
- 2 tablespoons cider vinegar
- 1 tablespoon brown sugar
- 1 1/4 pounds deli-sliced corned beef
- 4 slices (for open-faced) or 8 slices rye, pumpernickel, marble or white bread, toasted
- 2 cups of shredded Gruyere or cheddar cheese
- Spicy brown mustard, for topping
In a large skillet, heat the oil over medium-high heat. Add the cabbage and cook until wilted, 5 minutes; season with the caraway seeds (if using), salt and pepper. Add 1/4 cup of chicken stock, lower the heat and keep simmering.
In a medium saucepan, melt the butter over medium heat until foaming. Add the onions and bay leaf; season with salt and pepper. Cook, stirring occasionally, until the onions are light golden and very soft, about 15 minutes. Stir in the relish, vinegar and brown sugar; discard the bay leaf.
Preheat the broiler. In a small skillet, heat the remaining 1/4 cup chicken stock over medium-high heat. Turn off the heat and add the corned beef to warm through.
Arrange 4 slices of bread on a baking sheet. Using a slotted spoon, transfer the cabbage, corned beef and onion mixture onto the bread. Top with the cheese; broil until melted (top with remaining 4 bread slices, if using) and serve with the mustard and pickles.
