Lime Chiffon Pie

Mix 1 envelope unflavored gelatin, 3/4 cup sugar and 1/4 teaspoon salt in saucepan. Add 1 cup water and 1/3 cup lime juice; blend in 2 slightly beaten egg yolks. Cook and stir over medium heat to dissolve gelatin. Add 1 1/2 teaspoons grated lime rind; chill until slightly thickened. Beat 2 egg whites until foamy; beat in 1/4 cup sugar until stiff peaks form. Blend in gelatin mixture, 1 cup prepared DREAM WHIP Whipped Topping and 3 drop green food coloring. Chill until mixture mounds. Spoon into cooled baked 9-inch graham cracker crumb crust. Chill 4 hours; garnish.
