Matambre is a South American rolled Beef Flank, stuffed with Chimichurri, vegetables and hard boiled eggs in it's traditional form, for my version I'm just using the Chimichurri.

This is a massive feed, great for a party or a bunch of blokes watching a game!

I like to borrow from Vietnamese culture and turn it into a Bahn Mi by stuffing it into a crusty bread roll, like this it will feed an army!

Step 1: Ingredients

For the chimichurri sauce:

1 bunch fresh parsley leaves, stalks and all

1 bunch of coriander (cilantro)

6 large cloves of garlic

1/2 cup olive oil

1/4 cup red wine vinegar

2 tablespoons water

1 red onion

1 ½ teaspoons smoked paprika

1 teaspoon salt

2 fresh chillies (deseeded)

1 whole skirt steak

1 tablespoon dried oregano

3 or 4 fresh Bay leaves chopped

Step 2: Make the Chimichurri

This can be done the day before.

It's dead easy to make and great on a mixed grill BBQ, so I make it up and keep as jar in my fridge all summer!

To Make it, just blend all the Chimichurri ingredients together in a food processor.

It will keep up to a week in your fridge if you can resist using it on everything you eat!

Step 3: Prepare the Beef

Carefully slice through the skirt steak from the thin end, work with the grain as much as possible to butterfly it.

Stop just short of the edge so it remains one piece.

The idea is to "butterfly" the beef length-ways.

Step 4: Coat the Beef in Marinade

Fold the skirt out flat, cut side up and completely smother it with the Chimichurri.

Step 5: Refrigerate

Place in a container and pour over the remaining Chimichurri.

Cover and refrigerate overnight.

Step 6: Retrieve the Beef

Remove the beef from the marinade, using your hands wipe as much of the marinade off, back into the container.

Keep the Chimichurri Marinade for the next step.

Step 7: Reconstitute the Chimmichurri

Drain the Chimichurri through a sieve or muslin cloth to remove the excess moisture. I push mine through a sieve.

This forms the Chimichurri into a thick paste.

Step 8: "Stuff" the Beef

Lay the beef out flat, cut side up.

Cover with the drained Chimichurri.

Step 9: Roll the Beef

Roll the Beef so the grain of the meat is running the length of the roll.

This is the secret, this will mean you are cutting against the grain when you serve and the slices will eat well.

Step 10: Tie the Roll

Tie the Matambre tightly every inch along the length of the roll using butchers twine, with one tie about, like you were preparing it for a rotisserie, in fact cooking Matambre on a rotisserie would be a good thing!.

Season with salt and pepper.

Step 11: Cooking

BBQ at Low Temperature, roughly 130°C (266°F) for 8-9 hours till the meat is soft when probed with a skewer.

I'm just using my Weber kettle with a medium heat indirect fire on both sides.

Step 12: Slice and Serve

Remove from the BBQ and let rest for 10 minutes.

Remove the twine and slice into thin slices.

Step 13: BONUS: Matambre Bahn Mi

I’m taking a bit of a liberty here, but I love Bahn Mi and Matambre both and I have some left so I’m borrowing the Vietnamese Bahn Mi idea and bringing it home to Agrentina.
