Ingredients

  • 1

    tablespoon(s) olive oil

  • 1

    small onion, sliced

  • 1

    teaspoon(s) thyme leaves

  • Kosher salt

  • Pepper

  • 4

    slice(s) (½-inch-thick) rye bread

  • 1

    tablespoon(s) melted unsalted butter or olive oil

  • 1

    tablespoon(s) whole-grain mustard

  • 2

    ounce(s) Gruyère cheese, grated

  • 2

    slice(s) roast beef

Directions

1.Heat olive oil in a medium skillet over medium heat. Add onion, season with 1/4 teaspoon each salt and pepper, and cook, covered, stirring occasionally, about 5 - 7 minutes. Reduce the heat to medium-low, stir in thyme leaves and cook, uncovered, stirring occasionally, until the onions are golden brown, (add 1 tablespoon water to the skillet if the onions start sticking). 2. Brush one side of each slice of bread with butter or oil. Form sandwiches with the bread, whole-grain mustard, Gruyère cheese, roast beef, and the onion mixture. Cook the sandwiches, covered, until the bread is golden brown and crisp and the cheese has melted, 4 to 5 minutes per side.
