In a food processor, combine the strawberries and sugar; pulse until well mixed. Set aside.
2 cups chopped strawberries, ¼ cup granulated sugar
In the bowl of a stand mixer fitted with the paddle attachment, beat the whipped topping, lemonade concentrate, and sweetened condensed milk together until smooth and creamy. Add food coloring if desired.
8 ounces frozen whipped topping, 12 ounces frozen lemonade concentrate, 12 ounces sweetened condensed milk, 20 drops yellow food coloring
Pour the lemonade mixture into the pie crust
1 (6-ounce) premade graham cracker crust
Pour the strawberry mixture over the lemonade mixture and swirl into the top using a knife. (You may not need to use all the strawberry mixture, depending on the size of your crust. Pour a bit at a time as to not overflow the crust.)
Freeze for approximately 8 hours or overnight, until well frozen.
Slice and serve, garnishing with lemons and strawberries, if desired.
