Pre-heat the oven to 180°C/350°F and line a baking tray with baking paper. Spray a little olive oil over the baking paper
Arrange the Brussels Sprouts halves on the prepared baking tray. Spray some olive oil over the sprouts. Season lightly with pepper but no salt at this stage
Place the tray in the oven for 15-20 minutes until the sprouts are lightly charred and crispy. Rotate the sheet halfway through to ensure even browning
In the meantime, heat up the fry pan over a medium high heat and toast the peanuts. Once golden brown, remove and set aside
In the same pan, toast the sesame seeds until they start to turn golden brown. Remove and set aside
In the same pan, toast the Sichuan peppers until just about to smoke. Remove and set aside in a mortar and pestle
Lightly grind the Sichuan peppers in the mortar and pestle to release all the flavour
Lower the heat of the fry pan to the lowest setting. Combine the soy sauce, vinegar, and honey then add this to the fry pan
Add the Sichuan peppers, half of the sesame seeds, and chopped chilli and let all the flavours infuse and thicken to make the sauce
Add the roasted Brussels Sprouts fresh from the oven and toss everything through
When ready to serve, add the peanuts and remaining sesame seeds. Serve hot!
