Heat oven to 220C/200C fan/gas 7. Cut ciabatta into 12-18 thin slices. Arrange in 1 layer on a baking sheet.
Drizzle with olive oil, season and bake for 8-10 mins, or until crisp. Meanwhile, blitz olives, extra virgin olive oil, parsley, capers and garlic to a paste. Season with black pepper and spread on the ciabatta toasts.
