Place the tomatoes onto a baking sheet and drizzle with olive oil and a sprinkle of salt and pepper. Place them on a rack in the upper third of the oven under the broiler. Keep your eye on them, but after about 5- 6 minutes they should be starting to blister and begin to burst.
Smash them gently to open them up. Remove them to the bowl with the peppers.
Use the back of a wooden spoon to break open the blistered tomatoes to release their juices. Drizzle with 2 tbsp olive oil and 1 tbsp white balsamic vinegar. Sprinkle a generous amount of salt and pepper, to taste. Toss gently. Spoon a generous helping of the breadcrumbs over the salad. Serve warm.
