Chop the stale bread and place it in a large bowl with some water and vinegar. Squeeze the bread well and crumble it, then add the sliced tomatoes, onion, and cucumber. Season with salt and pepper to taste and plenty of Olio Extravergine d’Oliva Toscano IGP. Mix all and leave in the fridge for at least 15 minutes before serving. Garnish with some basil.
