Clean and chop the vegetables. I cut them coarsely for speed and ease.
Sauté the onion in a little oil.
Add the remaining vegetables when the onion is ready, along with enough water to cover them, but not too much to avoid a thin soup after blending.
Let it simmer on low heat for about 25-30 minutes.
A little before turning off the heat, add the spices: thyme, salt, black pepper, and savory. Optionally, you can add croutons by following this recipe.
