Open-Faced Grilled Ham and Cheese Sandwich
These pretty little sandwiches make a great lunch with a cup of tomato soup and can easily feed a crowd—simply scale up the recipe as needed, pop in the oven and you’re ready to go.
- Preheat the oven to 400°F. Brush a small sheet pan with olive oil.
- Arrange the slices of toast on the pan. Spread the mustard over the toast and top each with 1 slice of ham, 1 slice of cheese, 2 slices of tomato and a few slices of red onion.
- Drizzle each sandwich with olive oil and sprinkle lightly with salt and pepper.
- Bake until cheese is bubbling and melted, 10–12 minutes. Garnish with chives and serve at once.
