To prepare the Piperade vegetables, heat the olive oil in a pan, add the vegetables, garlic and sun dried tomato juice and season. Cover with a tight-fitting lid and leave over a low heat until the vegetables are just soft to the touch. Remove the vegetables from the heat and add the olives and basil to warm through. Pour over the pizza base. Sprinkle over the blue cheese and garnish with fresh herbs. Place in the oven at 200°C for approx 20 minutes.
