Preheat the oven to 350°F (180°C).

Place the bread slices in the oven and toast until golden brown.

Turn off the oven, use oven mitts to remove the baking sheet, and set it on the counter.

Rub a garlic clove over each slice of bread, then place the slices on a cutting board.

Wash and core the tomatoes, dice them, and place in a bowl. Season with salt and oregano, and mix well.

Arrange the bruschetta on a serving plate. Using a spoon, top each slice (on the side rubbed with garlic) with the tomato mixture, and serve.
