Whilst your Roccbox is coming up to temperature, make the Salsa Verdi by mixing all the ingredients together in a bowl and seasoning with black pepper. Set to one side.
To make the white sauce, mix the ricotta, olive oil and lemon juice and zest together before seasoning well and setting to one side.
Stretch each dough ball into your perfect pizza base and top with white sauce. Evenly dot around the mozzarella, smoked mackerel, tomatoes and samphire. Using your floured pizza peel, pop the base into your Roccbox and cook for around 90 seconds, turning regularly.
Remove from Roccbox and top with a generous helping of salsa verdi. Cut into slices and serve!
