Corned Beef Melts with Sweet & Sour Onions & Wilted Cabbage

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.
