If you're putting them on the barbecue, make sure it's hot. If using the grill, pre-heat it to medium-hot.
I'm showing them being cooked in a pan here so if you want to do them like this get the pan medium-hot.
Cook 5 or 6 at a time for a couple of minutes each side. Don't be tempted to overcook as they'll dry out.
Brush coconut oil once on each side as they're cooking to lock in the juices.
