Grill the bread slices over a moderately hot fire until they are nicely toasted on both sides, turning frequently to ensure even browning. Be careful not to burn them; they will cook in only a few minutes.
Now take a half garlic clove, which as indicated you have cut into two crosswise without peeling:
Rub each slice of bread while it is still hot with the exposed inside of the clove, squeezing the garlic between your fingers to release its juices into the bread.
Now drizzle your bread liberally with your fruity olive oil. The slices should be nicely soaked. Salt the slices to taste.
If you want, you can top each slice with the tomato mixture, which you make by mixing together all of the ingredients mentioned above in a bowl right before you serve your bruschetta.
