Portuguese Prego with Green Piri-Piri Sauce

Instructions

1. 1

   Marinate the Beef Fillets

   8 min

   Start by taking garlic and rubbing it thoroughly over the surface of the beef fillets to infuse flavor. Place the fillets into a resealable sandwich bag along with olive oil, sherry vinegar, and the leaves from parsley stalks. Seal the bag and gently pound the steaks using a rolling pin to help the marinade penetrate the meat. Allow the beef to marinate in the refrigerator for 1 to 2 hours for optimal flavor absorption.

2. 2

   Blend Green Sauce Ingredients

   5 min

   For the vibrant green sauce, combine the remaining sauce ingredients, including basil leaves, jalapeno, spring onions, and caster sugar, in a blender. Add about 1 tablespoon of water to help with blending and process until the mixture is completely smooth. This sauce will create more than is needed for the sandwich, so consider storing the extra in an airtight container for up to a week.

3. 3

   Sear the Beef Steaks

   2.5 hr

   Preheat your griddle or frying pan to high heat to ensure a good sear. Once hot, remove the garlic and parsley stalks from the marinated steaks and season the beef generously with salt and pepper. Sear the fillets for roughly 2 minutes on each side until they develop a nice brown crust. After cooking, let the steaks rest on a plate for a few minutes; during this time, place the ciabatta halves cut-side down on the plate to soak up the flavorful juices.

4. 4

   Assemble the Sandwiches

   4 min

   Once the steaks have rested, slice them into thin strips to enhance tenderness. Take the ciabatta rolls and generously fill them with the sliced beef, then drizzle over the prepared green sauce. Finish by adding a handful of rocket to each roll for a fresh, peppery contrast to the rich beef and sauce.
