Preheat a large skillet or griddle pan to medium high heat and cut the Brussels sprouts in half or quarters
Add prepared brussel sprouts to a mixing bowl and toss with a generous amount of oil and season generously with salt and pepper.
Once the pan is hot, add the sprouts, in stages so you do not overcrowd the pan.
Cook for 1 minute, then toss and turn them so they cook evenly on all sides.
Remove from the heat and immediately add back to the mixing bowl and top with minced garlic and season again with salt and pepper. Continue to cooking any other batches in the same way.
To serve, sprinkle with chilli flakes, parmesan cheese or herbs of your choice
