Strawberry Lemonade Slush
For approximately 200 people (10 oz cups)

10 1 lb. containers of fresh strawberries
16 frozen containers of pink lemonade
8 2 liters of Sprite
Crystal Lite Pink Lemonade powder
Water

For each batch:
In a blender or smoothie maker, add one container of partially thawed pink lemonade. Add one cup of water and about a handful or two of strawberries (minus the stems). Blend this up good. Add a little Crystal Lite powder to it to sweeten it a bit. Blend it again. Taste it to make sure it's sweet enough -- if not add a little more powder. Blend again. Pour it into a freezer Ziploc bag and place in the freezer. Repeat with all batches.

When time to serve:
Remove one bag at a time and let it thaw a bit. Place it in a bowl and dig at it with something like a big fork. Add Sprite to it until you have the right consistency. Serve immediately.

I did a taste test and found that Sprite was much better in it than 7-up!
