Select the sauté mode of an instant pot and add avocado oil.
Once the oil is hot, add chopped onions and cook for about 2 minutes or until they are tender.
Add garlic, green onions, and celery. Cook for a minute or two.
Add carrot, cabbage, fresh thyme sprig, fresh rosemary sprig, and Italian seasoning. Stir.
Pour in water, and add vegan bouillons and cayenne pepper.
Press cancel. Seal the instant pot tightly with a lid and lock it in place.
Now pressure cook at “high pressure” for about 10 minutes.
Once the time is up, naturally release the pressure, about 20 minutes.
Take the lid off, season with salt and pepper to taste
