For a richer flavor, consider using homemade chicken broth. Feel free to experiment with different types of cheese on the toast, such as Asiago or Pecorino Romano. If you don't have a toaster oven, you can toast the bread in a regular oven at 350°F (175°C) for about 8-10 minutes. A drizzle of good-quality olive oil over the finished soup adds a lovely finishing touch. Adjust the amount of garlic to your preference. For a milder flavor, use fewer cloves.
