In a medium bowl, whisk together the gelatin and 3/4 cup boiling water until the gelatin is dissolved. Add 3/4 cup iced water and stir well. Refrigerate until the mixture begins to thicken, about 30 minutes or so.
Stir in the strawberries. Pour the mixture into a 1-quart oval or rectangular shaped casserole dish and place in the refrigerator to set up.
Meanwhile make the creamy cheese layer: Place the cottage cheese in blender or food processor and process until very smooth. Add the cream cheese and pulse until it is combined with the cottage cheese. Scrape the mixture out into a medium bowl and stir in the sweetener and lemon zest. Then gently fold in the whipped topping. Cover and refrigerate.
When the gelatin has set, spread with the "cheesecake" mixture. Cover and refrigerate until ready to serve.
Just before serving, top with crushed pretzels so they don't get soggy.

However, I find everyone likes it so much it disappears in a hurry. To prevent the pretzels from getting soggy, sprinkle them on just before serving.
