    Please note that the TM5 mixing bowl has a larger capacity than the TM31 (capacity of 2.2 liters instead of 2.0 liters for TM 31). Recipes for the Thermomix TM5 may not be cooked with a Thermomix TM31 for safety reasons without adjusting the quantities. Risk of scalding by spraying of hot liquids: Do not exceed the maximum filling quantity and observe the filling level markings of the mixing bowl!

    Very tasty and easy to make. Kids requested leftovers for lunch the next day. Will definitely make again. I subbed peas for corn and used normal milk, plus added some extra chopped veggies also.
