• Using electic mixer, beat whites in medium bowl until soft peaks form. Scrape seeds from vanilla bean. Gradually add sugar, beating until meringue is stiff and glossy, about 5 minutes. Fold in ground almonds. Spread 1 rounded tablespoon of meringue in each circle on parchment, forming disks about 1/4 inch thick.
• Bake meringue disks 1 hour. Reverse position of sheets and bake until meringues are pale golden and almost firm to touch, about 45 minutes longer. Cool meringues on baking sheets. Carefully peel meringues off parchment.
• Arrange 8 meringues on clean baking sheet; top each with second meringue. Top each stack with scoop of sorbet (don't press; disks are fragile). Cover with foil; freeze while making vanilla meringue or up to 2 days.
