This soup is chock full of vegetables and herbs and tastes even better the second day after it's been made. The sesame seed parm is a nod to the traditional recipe and boosts the calcium and plant-protein and is just plain fun to sprinkle on.
Add the onion and garlic along with 1" water to a large stock pot over medium-high heat. Cook until the onion is translucent, then add in the carrots, celery and tomatoes. Cook another 1-2 minutes. Add all remaining soup ingredients, bring to a boil, then reduce heat to low. Simmer for 45-minutes to 1 hour or until the potatoes are tender. Adjust seasonings as needed.
Add all ingredients to a food processor or high speed blender and mix until thoroughly combined and the sesame seeds are crumbly and look like parmesan cheese. Can be stored in an air-tight jar in the fridge for 1-2 weeks.
I prefer this soup with the vegetables (especially the tomatoes and zucchini) finely chopped - or in the case of the zucchini, shredded. This especially helps when serving it to children who tend to be suspicious of large chunks of vegetables - or adults who feel the same way. ;)
