In a 3- to 4-quart saucepan heat oil over high heat. Add onion and garlic; saute until onion is translucent, 1 to 2 minutes. Add water and broth mixes and stir until dissolved. Reduce heat to low and add potatoes, tomatoes, carrot and bay leaf; cover and let simmer until vegetables are tender, 35 to 40 minutes. Add remaining ingredients and cook until sausage and chick-peas are heated through, about 5 minutes longer. Remove and discard bay leaf before serving.
