Make pizza base as per manufacturer’s instructions. On a semolina floured surface, hand stretch pizza base to the desired length, width and shape. Allow to rest for a few minutes.
Spoon pizza sauce over base and place remaining ingredients randomly onto pizza keeping back the Grana Padano and Watercress for garnish. Bake in the oven until pizza base is golden.
Remove from oven, garnish with cress and cheese, dress with olive oil and serve
