Brush the bread slices lightly on both sides with the olive oil.
Toast the bread slices (in batches if necessary) for 1-2mins on each side until golden. Set aside.
Place the tomato in a bowl with the garlic, basil and remaining olive oil. Season and stir to combine.
When ready to serve, pile the topping onto the bread and gently press down with a fork to hold the topping in place.
Serve on a napkin or waxed paper
