Instruction

• STEP 1 Rub the garlic over the steaks then put in a sandwich bag and tip in the olive oil, sherry vinegar and parsley stalks
• Smoosh everything together, then use a rolling pin to bash the steaks a few times
• Leave for 1-2 hours
• STEP 2 To make the sauce, put all the ingredients into a blender with 1 tbsp water and whizz until as smooth as possible
• This will make more than you’ll need for the recipe but will keep for a week in an airtight jar
• STEP 3 Heat a griddle or frying pan to high
• Brush away the garlic and parsley stalks from the steaks and season well
• Sear the steaks for 2 minutes on each side then rest on a plate
• Put the ciabatta halves onto the plate, toasted-side down, to soak up any juices
• STEP 4 Slice the steaks then stuff into the rolls with the green sauce and rocket
