Fire up your grill for medium-heat cooking.
Cut off the stems from the Brussels sprouts and remove any loose leaves.
Place sprouts in a large microwavable bowl and microwave on high for 3 minutes, stopping halfway through to stir.
Carefully remove the bowl from the microwave.
Combine the remaining ingredients and pour over the sprouts. Toss to coat.
Transfer the sprouts to a grill basket (optionally you can skewer them) and transfer to your grill.
Grill for 5 minutes. Stir and grill another 5 minutes or until the sprouts have a nice char on them.
