  1. Heat oil in a soup pot. Add onions and cook 15 to 20 minutes until translucent-don't brown. Add broth, water, salt, garlic powder and pepper. Bring to a boil. Reduce heat and simmer 45 minutes. Meanwhile, preheat oven to 325 degrees. Slice of tops of top bun to make the same thickness as the bottom bun. Place buns on a sheet pan and bake until golden brown and crisp, about 15 to 20 minutes. Set oven to broil.

  2. For each portion: Spoon 1 cup soup into an ovenproof bowl. Top with a bun half. Place a slice of provolone over and sprinkle with 1/2 tsp. parmesan. Broil 5 to 6 minutes until cheese is melted and starting to brown. Serve immediately.
