Preheat to the oven to 200C / 190C fan / gas 4
Tear the bread into bite sized chunks and put it on a lined tray and drizzle with the olive oil and add a pinch of salt. Toss to coat. Place in the preheated oven and bake until started to crisp and colour around the edges but still soft inside. Remove from the oven, put into a large bowl (you will mix all the salad in this bowl) and allow to cool slightly.
While the bread is baking, take half the tomatoes and add the garlic, olive oil, vinegar and half the bunch of basil and put in a blender. Season and blend until smooth, set aside
Pour the dressing over the bread and let the bread sit for five or so minutes
Add the remaining chopped tomatoes, rocket, cucumber, remaining basil, sliced red onion and capers to the soaked bread and stir to combine. Season, taste and adjust as required. Pile onto a serving plate and serve immediately.
