Directions
- Use the first 9 ingredients from the list for the grilled flat iron steak.
- Remove steak from package and dry with a paper towel and transfer to a sheet pan.
- In a small bowl mix salt, garlic powder, cumin, black pepper, chipotle pepper, paprika and red pepper flakes.
- Sprinkle and rub in half of the spice mixture evenly over the surface of the meat. Flip beef over and add the remaining spice mixture.
- Drizzle 1 teaspoon of the olive oil over the meat, rub the surface to coat. Repeat with the other side of the meat with 1 teaspoon of oil.
- Heat grill over medium heat.
- Add a small amount of vegetable oil on a folded piece of paper towel, and then carefully grease the grill with the oil.
- Once the grill is nice and hot, add the steak and grill uncovered flipping halfway through; 8 to 10 minutes for medium-rare (145°F), 10-12 for medium (150-155°F).
- Allow the steak to rest for 10 minutes before slicing. Cut into 1/2 inch thick slices.
- Use the last 8 ingredients from the list for the chimichurri sauce.
- Add all ingredients into a blender or food processor except for the olive oil. Blend for 20 seconds to break down the leaves.
- Slowly add 1/2 cup of the olive oil in the opening of the lid in a thin steady stream while the machine is running, until smooth and slightly thickened.
