On a parchment paper covered rimmed baking sheet, add tomatoes, onions, fresh basil and garlic. Sprinkle with salt, pepper, thyme 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 half cup of water to bowl and then blitz with immersion blender. Keep blitzing until smooth. Add water (a tablespoon, at a time) until sauce is at desired consistency.
NOTE: I would suggest thicker for pizza sauce, and thinner for pasta sauce.
