The recipe really only needs 2 ingredients: tomatoes and olive oil. The garlic and fresh herbs are optional. You can also season with Italian dried herb blend in place of the fresh herbs.
Heat oven to 425F. Place tomato halves on baking sheet. Drizzle with olive oil. Scatter garlic and herbs. Roast 25-30 minutes, until tomatoes softened.
2. Puree in blender or use a potato masher. To thicken, simmer for 5 minutes on stovetop. Season with salt to taste.
