First of all, bring around 700 millilitres of water to the boil in a saucepan and blanch your broccoli for a few minutes until al dente.
Remove the broccoli from the pan with a slotted spoon and place in a colander.
Pour cold water over your broccoli florets so that they don't cook further.
Now add your mung beans to the same pan of boiling water.
Reduce to a medium heat and cook for around 30 minutes until your beans have softened. You can do a taste test from 20 minutes onwards to make sure they don't overcook.
Whilst your beans are cooking, you can prep your other ingredients.
Add your broccoli, onions and coriander leaves to a large bowl and mix around.
When your beans are cooked, drain them in your colander and pour cold water over them.
Drain again and add them to your salad bowl and mix around.
Mix your salad dressing ingredients in a ramekin bowl, pour the dressing over your salad and mix.
Now add your avocado pieces and mix them in carefully so that they don't start to mash.
Divide the salad between two bowls.
Enjoy your mung bean salad as a light lunch or as a side dish.
