1. To prepare the capsicum, grill — turning occasionally — until the skin has blackened all over. Place in a plastic bag, until cool. Peel then thinly slice.
2. Top 4 slices of the bread with the cheese, rocket and capsicum. Top with the remaining bread. Butter each sarnie on the outside.
3. Pan-fry until golden on both sides and the cheese has started to melt.
