On a parchment paper covered rimmed baking sheet, add tomatoes, onions, fresh basil and garlic. Sprinkle with salt, pepper, and oregano. Drizzle with olive oil. Place in oven and bake for 30 minutes (a small bit of charring is fine, but don't let it burn).
Remove from oven and let rest 5 minutes. Then remove to a mixing bowl and let rest another 10 minutes.
Add Worcestershire, honey and paprika to bowl and then blitz with immersion blender. Keep blitzing until smooth.
Transfer to large pot and place on stove over medium heat. Let bubble and simmer for 30 minutes. Serve with a swirl of olive oil over the top.
