Here is a beautiful recipe that I commonly use when having grilled steak.

Ingredients

2 cups chopped parsley
2/3 cup extra-virgin olive oil
6 tablespoons fresh lemon juice
2 tablespoons minced garlic
2 teaspoons crushed red pepper
Salt and freshly ground pepper
4 pounds skirt steak

Recipe

1. Light a grill. In a bowl, mix the parsley, olive oil, lemon juice, garlic and crushed red pepper; season with salt and pepper.

2. Season the skirt steak with salt and pepper and grill over a hot fire until the meat is charred on the outside and rare within, about 2 minutes per side. Transfer to a carving board and let rest for 5 minutes. Thinly slice the steak across the grain. Serve right away, passing the chimichurri sauce at the table.
