Wash lettuce and other greens (if using). Shake off excess water well and tear into big chunks.

Mix the soy sauce, salt, sugar, pepper powder in a bowl and set aside.

Smash the ginger and garlic cloves.

In a wok or non-stick pan, heat sesame oil.

Add the smashed ginger and let it sit in the oil for a few seconds so allow the oil to be infused with flavour.

Add the garlic cloves and give it a quick stir.

Throw in the lettuce and toss well, making sure you cover them in the oil mix as thoroughly as possible.

Switch to high flame.

Pour in the sauce mixture and give the lettuce (and greens) a good mix.

Remove from heat when the lettuce is tender but have a slight crunch.

Sprinkle with some white sesame seeds.

Serve immediately.
