No Bake Strawberry Lemonade Freezer Pie

No Bake Strawberry Lemonade Freezer Pie 
1 premade graham cracker crust
1 tub low fat cool whip
1 (12 ounce) can lemonade concentrate
1 can low fat sweetened condensed milk
2 cups strawberries (frozen or fresh), chopped
¼ cup sugar
20 drops yellow food coloring (optional)
lemons and strawberries for garnish
In a food processor, combine strawberries and sugar and pulse until well combined. Set aside.  In an electric mixer, combine cool whip, lemonade concentrate, and sweetened condensed milk with paddle attachment. Mix until smooth and creamy.  Pour lemonade mixture into pie crust.  Pour strawberry mixture over lemonade mixture and swirl into the top using a knife. (You won't need to use all the strawberry mixture depending on 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!
