Preheat the oven to 180˚C.
1. Chop the pepper, courgette and mushrooms into cubes and drizzle with olive oil, salt, pepper and mixed herbs. Add them to the preheated oven for 15-20 minutes.
2. In the meantime, prepare the sauce. Heat the olive oil in a pan and add the garlic, thinly slice the shallot and add it to the pan with the oregano. Allow to sweat for 2-3 minutes before adding the tomato puree and chopped tomatoes. Bring to the boil and then leave to simmer for 20-25 minutes.
3. Now it’s time to assemble the pizza. Add a few tablespoons of sauce to the wholemeal pitta and top with the vegetables and sweetcorn. Finish off with the mozzarella cheese and return to the oven for a further 5-8 minutes. Option to serve with fresh basil.
