My work does a Kris Kringle Lunch and we all bring something. I've decided to take Mocktails... but I can't find any receipes!!!! Can anyone help me out? They need to be something I can make the night before or quick and easy to make on the day (I'm happy to take my little blender to work but it really has to be quick and easy if I'm doing it at work... gotta still look after my patients!)

TIA
