Preheat the oven to 375 degrees . Place the bell pepper, carrot, onion and garlic in a food processor; pulse until the mixture is finely chopped. In a medium skillet, heat the oil over medium. Add the chopped vegetables and cook until softened, about 5 minutes; cool.
In a large bowl, combine the vegetables, turkey, pork, breadcrumbs, eggs, ketchup, Worcestershire sauce and 1 1/2 tsp. salt; mix well. Place the meat mixture in a 9-by-13-inch baking dish and, using your hands, form it into a loaf.
Weave the bacon slices over the meat loaf. Bake, uncovered, until cooked through, about 1 hour.
Transfer the meat loaf to a platter. Slice.
