Soak the bread in water with a few tablespoons of vinegar for 20-25 minutes, until it softens but does not become mushy.

Cut the cherry tomatoes and slice the onion. If the onion is too strong, soak it in cold water for a few minutes.

Gently squeeze the bread to remove excess water, break it into large pieces, and place it in a bowl with the tomatoes and onion. Mix everything together, adding salt, olive oil, oregano, and basil. Refrigerate for at least 1 hour, then let sit at room temperature for 15 minutes before serving.
