Preheat oven to 350°F.
Unwrap the Nature Valley™ granola bars and add them in a food processor and process until you achieve a fine crumb.
Reserve half of the crumbs (about 3/4 cup) for topping. There will be a bottom and top layer of crumbs.
In a large bowl, combine half of the crumbs with the brown sugar, flour, and melted butter.
Spread crumb mixture into an 8x8-inch baking dish that has been covered with parchment paper and bake at 350°F for 10 minutes. Let cool.
In another mixing bowl, combine eggs whites and sugar and mix on high.
Add the heavy cream and continue mixing for another 5 minutes.
In another bowl, mix squeezed lemon juice and softened cream cheese. Mix on low speed until incorporated. Add heavy cream mixture.
Fold the fresh strawberries into the cream mixture.
In a buttered glass dish, press the butter-crumb crust mixture that you baked, on the bottom of the pan.
Top that with the strawberry mix and then add the reserved granola crumbs to the top!
Cover and freeze for three hours or more and enjoy!
