Cold bread soup from Bari with tomatoes, onion, and olive oil is Puglia's summer refresher. A vegetarian mediterranean dish that's healthy, fresh, and perfect for hot-weather family meals.
Slice the stale country bread into bite-sized cubes and place in a wide bowl.
Dice ripe tomatoes, slice the red onion thinly, and cut the cucumber into half-moons; scatter all over the bread.
Drizzle the extra virgin olive oil evenly, then sprinkle with sea salt and black pepper for well-balanced seasoning.
Toss everything gently with your hands to allow the bread to soak up the tomato juice; add fresh basil leaves last to retain their aroma.
Let the mixture rest for 10–15 minutes at room temperature so flavors meld and the bread softens without turning mushy. Serve chilled or at room temperature.
