Begin by breaking up the broccoli stem into small florets about the size of a mushroom. Half all the mushrooms lengthways. Slice a red onion into quarters and pull the onion layers apart into separate pieces.
Prepare the dressing. Take 2 tablespoons of soy sauce, 1 finely chopped red chilli, 1 finely chopped clove of garlic, 1 finely chopped lump of peeled ginger (about a garlic clove size) and 3 tablespoons of water, mix all together in a cup.
Place the broccoli, mushrooms and onion into a large hot wok and begin to stir fry with a little oil.
After a few minutes when the broccoli has started charring, pour in the dressing and continually stir until everything is coated. At this point I usually put a tight lid on the wok to allow the vegetables to steam slightly.
After a few minutes when the mushrooms have a colour to them, squeeze over the juice of a lime and the chopped coriander and stir.Serve immediately.
