Place a large Dutch Oven on medium high heat. Drizzle in the olive oil and cook the onions, carrots and celery for 10-15 minutes, or until soft.
Add the minced garlic and salt to the veggies and cook for 2 minutes before adding the split peas. Continue by adding the water and bay leaves to the pot.
Add the ham bone to the Dutch oven. Bring the soup to a boil. As soon as it boils, turn it down to a simmer and place the lid on the pot.
Simmer for 2 ½ hours, or until the split peas have broken down.
Once cooked, remove the ham bone from the soup. You could use an immersion blender to smooth out the texture of the soup. Take the meat off of the ham bone, break it apart and place it back into the soup.
