Heat oven to 350°F. On ungreased large cookie sheet, turn 5 (6-oz) custard cups upside down; spray outsides of cups with cooking spray. Separate dough into 5 biscuits; press each to form 6-inch circle. Press each biscuit over bottom and around side of each cup. Using fingers, press dough around each cup, forming bowl. Bake 15 to 18 minutes or until golden brown. Carefully remove custard cups. Set aside. Cool completely, about 5 minutes.
Meanwhile, in large bowl, mix dressing ingredients with wire whisk; fold in shrimp. Set aside. In small microwavable bowl, microwave peas about 30 seconds or just until heated through. Refrigerate while biscuit bowls cool.
Place biscuit bowls on serving plates. Fold oranges, peas, lettuce and onions into shrimp and dressing. Spoon into biscuit bowls. Serve immediately.
