Place egg whites in a large bowl; let stand at room temperature for 30 minutes. Line a baking sheet with parchment paper; set aside.
Add the vinegar, cream of tartar and salt to egg whites; beat on medium speed until soft peaks form. Gradually beat in sugar, 1 tablespoon at a time, on high until stiff glossy peaks form and sugar is dissolved. Fold in cocoa and chocolate.
Spread into a 9-in. circle on prepared pan, forming a shallow well in the center. Bake at 250° for 45-55 minutes or until set and dry. Turn off oven and do not open door; leave meringue in oven for 1 hour.
In a small bowl, combine raspberries and strawberries. Drizzle with 1 tablespoon liqueur; toss gently to coat. In a small bowl, beat cream until it begins to thicken. Add confectioners' sugar and remaining liqueur; beat until soft peaks form.
Top meringue with berries. Arrange kiwi over berries; top with whipped cream. Refrigerate leftovers.
