If you plan on adding barley, soak it in cold water overnight.
Add 1 cup chickpeas, onion, garlic, Italian parsley, semolina, bulgur, and spices to a food processor. Pulse until the ingredients are ground and come together. Use walnut-sized portions to form football-shaped dumplings.
Prepare the Soup
Heat oil in a medium-sized pot. Add chopped onions and zucchini and saute for a few minutes. Dissolve tomato paste into 7 cups of hot water and stir in salt, paprika, crushed red pepper, and citric acid. Pour liquid into the pot.
Add the remaining chickpeas and their liquid and barley (if using). Top with chopped Swiss chard (or spinach), Italian parsley, and garlic. Stir to combine, then bring to a boil.
Stir in dumplings then cover the pot with its lid and simmer over low heat for 30 minutes, until thickened.
Notes
For a thinner soup, leave out the barley and don't add the aquafaba.
I like the soup spicy, but for a milder chickpea soup, don't add the crushed red pepper.
The Swiss chard gives the soup an earthy flavor. You may want to substitute spinach instead.
To add even more flavor, you can use chicken broth or vegetable broth instead of water.
I recommend sprinkling some Parmesan cheese on top if you're not worried about keeping this dish vegan.
Store any leftover soup in an airtight container in the refrigerator for up to a week.
Reheating leftovers couldn't be easier! Choose from reheating the chickpea soup on the stovetop or in the microwave.
