Thinly slice all of the onions. Heat your soup pot on high on the stove. Once it is hot add the oil.
Once the oil starts to smoke add your onions. Cook the onions until they are wilted down and caramelized, about 20 minutes. Do not stir the onions for the first 4 minutes.
Next add the beef broth, bay leaf, Italian seasoning, salt, and pepper to the pot.
Cook the soup on medium heat for 30 minutes.
Ladle the soup into your bowl or ramekin.
Place a few pork rinds on top, and then sprinkle generously with grated cheese.
