Preheat oven to 400 degrees. Stir together crushed pretzels, melted butter and 3 TBS sugar; mix well and press mixture into bottom of a 9- by 13-inch baking dish. Bake 8 to 10 minutes, until set. Set aside to cool.
In a large mixing bowl, cream together cream cheese and 1 cup sugar. Fold in whipped topping. Spread mixture onto cooled crust.
Dissolve gelatin in boiling water. Stir in still-frozen strawberries and allow to set briefly. When mixture is about the consistency of egg whites, pour and spread over cream cheese layer. Refrigerate until set.
