Note: To get fast results, chop the vegetables first.
Heat one tablespoon of oil and water in a pot and add all the vegetables, salt, and pepper.
Stir the mixture until the vegetables are softened.
Add more water and bay leaves and bring the mixture to the boiling point.
Once boiled, reduce the heat level and add tomato paste. You can also add nutritional yeast however it is optional.
Continue cooking at a low heat level for about half an hour. The more you cook, the more the rich flavor will be.
On completion, taste the broth, adjust the flavors accordingly and let it cool.
Finally pour it in a container.
