Take your chicken breasts and slice in half lengthways to create long, thin halves. (This will help them to cook evenly). Place in the Varoma tray.
Add 500g water to the Thermomix bowl.
OPTIONAL STEP: to add extra flavour to the chicken, add some aromatics to the water. For example, ½ onion, garlic cloves, cloves, a bay leaf and a sprig of thyme or oregano.
Place the lid and Varoma on top of the bowl and cook for 15 minutes / VAROMA / speed 1.For TM7 - use Steaming mode / 15 minutes. Check to see if the chicken is cooked. If not, turn it over and cook for a further 5 minutes / VAROMA / speed 1.
Cut each piece of chicken in half and set aside to cool for 5 minutes.
Empty out the water from the Thermomix bowl. Place the chicken in the bowl and shred for 3 seconds / REVERSE / speed 4.
Store in fridge for up to 4 days.
