Heat oven to 350°F. Grease and flour 2 8×4 or 9×5-inch loaf pans. For easiest removal, cut 2 small pieces of parchment paper to line the bottoms of the pans; grease paper. In food processor, place beans and 1/4 cup of the juice. Cover; process 1 minute or until smooth. Add remaining orange juice, eggs, sugar, butter and orange peel. Cover; process 1 minute or until well mixed and smooth.
In large bowl, mix flour, baking powder, baking soda, cinnamon, nutmeg and salt with a wire whisk until well blended. Pour bean mixture over dry ingredients. Fold in only until dry ingredients are all moistened. Fold in zucchini and chocolate chips. Spoon evenly into pans.

In small bowl, mix powdered sugar and 1 tablespoon orange juice. Spread thinly on warm loaves. Cool completely before slicing or wrapping. Store in refrigerator.
