Place potato in a saucepan; cover with water. Bring to a boil; cook 20 minutes or until very tender. Drain. Cool slightly. Coarsely chop, and place in medium bowl. Add 1 tablespoon oil and garlic to bowl; mash potato mixture with a potato masher until slightly chunky. Remove 3 tablespoons chickpeas; place in a small bowl. Add remaining chickpeas to potato mixture; mash until well blended. Stir in remaining 3 tablespoons whole chickpeas, parsley, and remaining ingredients. With moistened hands, divide mixture into 6 equal portions (about 1/3 cup mixture per portion), shaping each into a 3-inch patty.
Heat 1 tablespoon oil in a large nonstick skillet over medium-high heat. Add 3 patties to pan; reduce heat to medium, and cook 4 minutes or until bottoms are golden. Carefully turn patties over; cook 3 minutes or until bottoms are golden and patties are set. Repeat procedure with remaining 1 tablespoon oil and 3 patties.
