Recipe adapted from John Besh's My Family Table (Andrews McMeel Publishing; 2011).
Preheat oven to 350 degrees. On a rimmed baking sheet or in a casserole dish, place tomatoes, cut side up, and season with salt and pepper. Drizzle with 2 tablespoons oil. In a food processor or blender, combine 1/2 cup oil, breadcrumbs, Parmesan, garlic, and basil and process until combined, 20 seconds (mixture should have a wet, crumbly consistency). Season with salt and pepper. Top each tomato half with 1 heaping tablespoon breadcrumb mixture. Bake until tops are browned and tomatoes are warmed through, 20 minutes.
