Drain the soaked chickpeas and rinse them well under cold water. Place them in a large pot with fresh water or broth. Bring to a boil, then reduce heat and simmer until tender.
Heat olive oil in a pot and sauté onions until soft and translucent. Add garlic, carrots, and celery, cooking until fragrant. This step builds the base flavor of the stew.
Add the cooked chickpeas along with oregano, salt, and pepper. Pour in broth and let everything simmer together. This allows all the flavors to blend beautifully.
In a bowl, mix flour, baking powder, salt, water, and olive oil. Stir until a soft dough forms. Avoid overmixing to keep dumplings light and fluffy.
Drop spoonfuls of dough directly into the simmering stew. Cover the pot and let them cook gently. The steam helps them puff up and cook through.
Once dumplings are cooked, stir in fresh lemon juice. Taste and adjust seasoning if needed. This final touch brightens the entire dish.
