Place all the tapenade ingredients into your food processor and pulse 15 times. Scrape down the sides of your processor bowl and then pulse 15 - 20 more times, until everything is finely chopped. Transfer to a bowl and set aside.
Slice your tomatoes in half. Using a hand or box grater, grate each tomato half over a bowl, until all of the flesh has been removed and all that is left are the empty skins. Discard the skins. Make sure to scrape any tomato bits that are stuck inside of the grater into the bowl. Stir the grated tomato in the bowl.
Toast your bread slices and while the bread is still warm, take a garlic clove half and rub it over the slices of toast to season. Spoon grated tomato onto your toast slices, followed by some Olive Tapenade. Add a sprinkle of black pepper to taste. Slice your toast in half and enjoy.
