Preheat the oven to 190°C.
Cut the onion and pepper into thin slices, the courgette into small chunks, then scatter them into a baking tray. Put the tomatoes on top, with the vine, and add the minced garlic, oil and balsamic vinegar, then toss well. Season to taste.
Put the tray in the oven and bake for 15 minutes or so, until the veggies are soft and tomatoes are bursting.
Meanwhile, cut the bread into chunks, put them on another baking tray, then toss with the oil and the dried herbs. Bake them for 5 minutes or so, shaking them once or twice to brown evenly.
Take the roasted veggies out of the oven, remove the vine, then toss the veggies with the croutons.
Serve with fresh herbs scattered on top. Season to taste.
