Add 1 tbsp oil to a medium-sized pot over low-medium heat. Add the grated onion & garlic and fry until they just begin to take on colour. Add in the tomato puree and fry for a couple of mins.
Pour in the tomatoes and swill out the can with a splash of water. Stir in the oregano, basil, sugar, chilli flakes, salt & pepper and bring to a simmer. Immediately reduce heat to low and simmer with the lid on (slanted to allow some steam to escape) for 30-40mins, or until thick and no longer watery, stirring occasionally.
Meanwhile, one by one lay cling film over the chicken breasts and pound them to even thickness (don't pound so thin they start breaking apart).
In a small bowl combine 1 tsp garlic powder, oregano & salt with 1/2 tsp black pepper.
Line up 3 bowls - the first with flour and half the chicken seasoning stirred in, the 2nd with 2 beaten eggs and the 3rd with Panko, parmesan and the rest of the seasoning. Coat the chicken in the flour, then egg and finish with a coating of the parmesan Panko. Ensure the chicken is thoroughly coated at each stage, especially in the Panko.
Add 1 cup of oil to a large heavy-based pan over medium heat (or enough to cover just over halfway up the chicken). You want the oil around 350F/180C -drop a few crumbs in to test if they rapidly bubble. Carefully place chicken in 2 breasts at a time and fry for 3-5mins on each side, or until golden on the outside and white through the centre. Place on a wire rack above a tray and repeat with the second two breasts.
Top the chicken with pizza sauce, then mozzarella, followed with peperami, pepper and olives. Place under the grill until the cheese is golden and bubbly. Serve up and enjoy!
