Preheat the oven to 425 degrees. Add all of the tomato ingredients to a baking dish and toss to combine. Place in the oven and bake for 20-25 minutes, or until they start to burst. Remove from the oven and allow to cool slightly.
While the tomatoes are roasting, prepare the dip. Add all of the dip ingredients (through the dry seasonings) to a food processor. Pulse until smooth, scraping down the sides as you go. It will take between 3-5 minutes to get a completely smooth texture. Place in the fridge to chill for at least 30 minutes.
To assemble, spread the dip in a shallow platter. Top with the tomatoes, being sure to add plenty of the juices/oil from the baking dish. Spoon over Calabrian chili paste to taste and top with fresh basil.
Serve at room temperature with toasted baguettes.
