Pre-heat oven to 400°F. Spray a baking dish (9"x9" or 9"x13") with cooking spray.
Cut the cores from the tomatoes and then slice them in half, horizontally. Remove the seeds and some of the cavity of the tomato halves with a small knife.
In a bowl, combine the bread crumbs, scallions, basil, parsley, thyme, garlic, and 1 teaspoon of Kosher salt.
Generously sprinkle the tomato halves with salt and pepper.
Mound the tomato cavities with the bread crumb mixture. Use a spatula to transfer the stuffed tomatoes to the prepared baking dish.
Bake the tomatoes for 15 minutes. Remove the tomatoes from the oven and sprinkle with the cheese, drizzle with olive oil and bake for another 2 minutes, or until cheese has just melted.
Serve warm or at room temperature.
