Step 3Reduce heat to low and stir in tomato sauce, ketchup, Worcestershire, apple cider vinegar, and brown sugar. Let simmer until slightly thickened, 5 to 7 minutes. Step 4To a large baking dish, add peppers. Divide the mixture evenly into 8 pepper halves and top with cheese. Pour beef broth into baking dish (to help peppers steam) and cover with foil. Step 5Bake until peppers are tender, about 45 minutes. Uncover and broil until cheese is golden, 2 minutes.Step 6Garnish with green onions and serve immediately.
