In a pot, heat the oil over medium heat, then add the onion, carrots, and celery. Sauté for about 7 minutes.
Stir in the garlic along with the seasonings and continue to cook for an additional 3 minutes.
Add the remaining ingredients to the pot and let the mixture simmer for 20 to 25 minutes, or until everything is tender.
If using an Instant Pot, cook on high pressure for 10 minutes and allow for a natural release for 5 minutes.
Once the soup has cooled completely, serve it with toasted bread.
