Preheat oven to 400 degrees and set a rack in the middle level. Brush a shallow baking dish with olive oil. Core the tomatoes and slice in half crosswise. Gently squeeze and scoop out all the seeds with a finger. Arrange the tomato halves in the baking dish and season with salt and pepper.
In a medium bowl, stir together the bread crumbs, Rose Canadian Bacon, green onions, herbs, cheese and parsley. Add a couple tablespoons olive oil and mix well till bread crumbs are moistened. Stuff the tomato halves with the mixture mounding it up on top. Drizzle a little olive oil over each tomato and bake for about 20 minutes till top starts to brown and tomatoes are hot.
