Chop the tomatoes and slice the cucumber and red onion.
Chop the bread in cubes (or break roughly with your hands) and put into a bowl with white wine vinager (apple cider vinager is fine too)*
In a salad bowl add all the ingredients and chopped basil. Add oil, salt and pepper to taste.

Notes
Bread soaked in vinager is the traditional way to serve the bread for this recipe but a variation is to add spices and oil and bake the chopped bread in the oven or air fryer, this will make the bread flavoursome and super crunchy
