EAS Carb Control Ready to Drink Shake, turned into ice cream:

Freeze a RTD protein shake overnight. Remove it mid afternoon and put it in the refrigerator. When you’re ready to eat it, remove it from the carton, cut it into chunks and put them all in a Ninja blender. Pulse gently – just a few pulses will do it – until it forms more of a ice cream or sorbet consistency.
