Preheat oven to 180 °C.
Line 2 large baking trays with baking paper. Grease with olive oil.
Slice the tomatoes in half and arrange cut side down on baking trays.
Roast for 15 minutes or until tomato skin is slightly charred.
Remove from the oven and let cool.
Once cool, remove and discard the skin. Set tomatoes aside.
In a large, deep pot over medium heat spray with olive oil, add onion and garlic and stir-fry for 2-3 minutes.
Add tomatoes and mash with a potato masher to break the tomatoes up, then add in water.
Simmer until liquid begins to reduce, about 30 minutes. Stir in oregano, parsley, basil, thyme, cracked pepper and red wine and simmer for a further 10-15 minutes.
Remove from the heat and allow to cool.
Once cooled, add to the food processor or use a stick blender and process gently.
