Ingredients

1 slice Italian bread, 1/2 inch thick 

Extra-virgin olive oil 

1/4 cup finely grated Parmesan 

2 slices heirloom tomato, 1/2 inch thick 

Red-wine vinegar 

Flaky sea salt, such as Maldon 

Freshly ground pepper 

Fresh basil leaves, torn if large 

Preparation

Brush both sides of bread with oil, then pat cheese evenly onto both sides.

Heat a dry nonstick skillet over medium. Add coated bread and cook, flipping once, until cheese is golden brown and melted, about 5 minutes.

Place one tomato slice on a plate. Sprinkle with vinegar, then drizzle with oil; season with salt and pepper. Layer with toast and remaining tomato slice. Sprinkle with vinegar, then drizzle with oil; season with salt and pepper. Top with basil and serve.
