Cut off stems of artichokes; remove bottom leaves. Trim about 1/2 inch from top of each artichoke. Place artichokes, stem ends down, in a large Dutch oven filled two-thirds with water. Add juice to water; bring to a boil. Cover, reduce heat, and simmer 40 minutes or until a leaf near the center of artichoke pulls out easily. Place artichokes, stem sides up, on a rack to drain.
Remove bottom leaves and tough outer leaves from artichokes; remove fuzzy thistle from bottoms with a spoon.
Mash beans in a medium bowl; stir in parsley and remaining ingredients. Spoon bean spread into centers of artichokes.
