Lemon Chiffon Pie

Why I Love This Recipe
I made this up with my friend's mom in honor of her baby shower. I have never really made pies before this, so I was glad that she was there to help!!!
Ingredients You'll Need
1 ready pie crust(you could make it from scratch, but I was scared!)
14 oz. sweet condensed milk (I use the fat-free kind)
2 cups sour cream (I think it sounds disgusting, but her mom recommended it and it didn't taste too bad. I used fat-free)
2 tbsp powdered pre-sweetened lemonade mix (I was lazy. I think I used maybe Kool-aide?)
4 drops yellow food coloring (if you really care if it looks like lemons)
8 oz. whipped topping (I used Cool Whip Free)
Directions
Prep the pie crust like the directions say, or how you would if you made it from scratch.
Combine the milk, sour cream, lemonade mix and food coloring in large bowl and mix well.
Fold in the whipped topping carefully until well blended.
Spoon into the crust and refridgerate for 2+ hours.
