Preheat oven to 400 degrees. Remove the stems and cut the tomato in half crosswise. Using a spoon (or carefully with a knife) remove the seeds and juice from the tomato. Sprinkle the halves with salt and pepper.
Break apart stale bread into smaller pieces and add to a parchment paper lined baking sheet. Season with salt, pepper and coat generously with olive oil. Bake for about 15 min or until the bread is browned. Let cool and then transfer to a food processor and blend until you have breadcrumbs.
Add garlic, green onions, basil, parsley, thyme and olive oil to the food processor with the breadcrumbs and pulse a few more times until everything is combined.
Drizzle the inside of the cocotte with olive oil and brush until all sides are coated. Fill each tomato with the mixture and then drizzle with a few more drops of olive oil. Roast for about 8-10 minutes until tops are browned. Top with a little grated parmesan cheese (optional). Enjoy!
