Portuguese prego with green piri-piri

Instructions

1- 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.

2- Smoosh everything together, then use a rolling pin to bash the steaks a few times.

3- Leave for 1-2 hours.

4- STEP 2 To make the sauce, put all the ingredients into a blender with 1 tbsp water and whizz until as smooth as possible.

5- This will make more than you’ll need for the recipe but will keep for a week in an airtight jar.

6- STEP 3 Heat a griddle or frying pan to high.

7- Brush away the garlic and parsley stalks from the steaks and season well.

8- Sear the steaks for 2 minutes on each side then rest on a plate.

9- Put the ciabatta halves onto the plate, toasted-side down, to soak up any juices.

10- STEP 4 Slice the steaks then stuff into the rolls with the green sauce and rocket.
