Preheat the grill to medium.
Brush the bread with a little olive oil, then toast in a hot frying pan for two minutes on both sides, or until golden-brown and crisp.
Spread the cheese over each slice of toasted bread, then place under the grill for 1-2 minutes, or until the cheese is melted and golden-brown.
Place the olives, garlic, freshly ground black pepper and a little olive oil into a mini food processor and pulse to a coarse paste. Slowly add a little more olive oil, continuing to blend, until the mixture comes together to form a smooth paste.
To serve, spread a little of the olive tapenade over each slice of toast and dot with a bit more cheese. Serve immediately.
