Step 1

Preheat oven to 350°F. For crust, in a food processor combine pretzels and almonds; cover and process until finely crushed. Add butter; cover and process until combined. Press mixture onto bottom and up side of a 9-inch pie plate. Bake 8 to 10 minutes or until light brown. Cool on a wire rack.

Step 2

In a medium bowl pour the boiling water over gelatin; stir until gelatin is dissolved (about 2 minutes). Cover and chill 30 minutes or until mixture is partially set (consistency of unbeaten egg whites). Fold in the next three ingredients (through lime zest). Pour into crust. Cover and chill at least 4 hours.

Step 3

If desired, top servings with lime slices and additional whipped topping and lime zest.
