Slice tomato in half crosswise. Scoop seeds out of the tomatoes. Sprinkle the tomato halves half the salt and pepper.
In a medium bowl, combine the garlic, shallot, thyme, red pepper flakes, parsley, breadcrumbs and the remainder of the salt and pepper. Stir to blend. Drizzle one tablespoon olive oil into the breadcrumb mixture while tossing to coat.
Spoon the breadcrumb mixture over the tomatoes. Drizzle with remaining olive oil and bake for 15-18 minutes or until crumbs are golden and tomato is slightly softened, but still holding its shape. Serve.
