In a large stockpot, heat olive oil over medium-high heat. Add diced onion, carrots and celery and saute about 5 minutes, until softened. Add in zucchini, red bell pepper and saute 2 minutes, then add garlic and cook 1 minute longer.
Add in vegetable broth, crushed tomatoes, rosemary, thyme, season with salt and pepper to taste. Bring mixture to a boil, then reduce heat to medium and allow soup to gently boil, covered for 20 minutes.
Add in dry quinoa and green beans then cover and cook 10 - 15 minutes longer.
Add cannellini beans, chick peas, kale, parsley and lemon juice and cook, uncovered, until kale has wilted, about 5 minutes.
Serve warm garnished with parmesan cheese if desired.
Notes
*Recipe originally called for 4 cups vegetable broth and 3 cups water but for more flavor I've omitted the water and increased broth. Also 1 1/2 tsp sugar have been omitted from the recipe, but if you think it needs it feel free to add it.
*You don't have to use unsalted broth and crushed tomatoes but if you are watching your sodium intake it's recommended.
**1 Tbsp dried Italian seasoning can be substituted for the thyme and rosemary.
