Heat olive oil in a large pot. Add carrots and celery, and sauté until some browning starts to happen around the vegetables.
Add chickpea flour and sauté until golden.
Add salt, black pepper. turmeric, cumin, fresh thyme leaves, bay leaves, and nutritional yeast. Sauté until aromatic. Add tamari and sauté for another 30 seconds or so. Adjust heat accordingly so that you don’t burn anything.
Add cooked chickpeas, half of the chopped parsley, and 8 cups of liquid. This liquid can consist of chickpea cooking liquid, chickpea liquid from the can, water, vegetable stock, or a combination of these. The total amount of whatever liquid you use should be around 8 cups. I used my chickpea cooking liquid and water. Bring to a boil. Skim off any foam on top. Reduce to a simmer and cover with lid. Simmer for about 30-45 minutes.
In the meanwhile, prepare the pasta. Bring a pot of salted water to boil. Add pasta and cook until slightly under al dente. If the package instructions say 7-10 minutes, aim for 5 minutes. The pasta will cook a bit more once mixed with the hot soup, so better to slightly undercook than overcook. Drain and rinse pasta under cold water. Set aside.
Once the soup is cooked and all the flavors have developed, turn off the heat, and add kale (or spinach), the remaining half of the parsley, and lemon juice. Stir well, and serve over cooked pasta noodles in a bowl.
