Instructions
Start with making the Chimichurri sauce. Place cilantro, parsley, garlic, oregano, salt, pepper, and red pepper flakes in a food processor. Process for 30 seconds or until they are combined. Add red wine vinegar and pulse 3 times. Turn on the processor and slowly add the olive oil and mix for 10 seconds.
Place it in a bowl and add minced capers. Taste for seasoning and adjust if necessary. Set aside and let all the flavors marinade in room temperature.
Season both sides of the steak with salt and pepper.
Heat 1 tablespoon olive oil in a cast iron skillet over medium heat until smoking.
Place the steak in skillet and cook each side for 3.5 -4 minutes. After the second side is cooked, add 1 tablespoon of butter into the pan. Spoon the melting butter over the steak and make sure it is all coated with it. Take it off the heat and let it sit in room temperature covered with aluminum foil for 5-10 minutes.
Place the meat on a cutting board and slice diagonally into 1-inch pieces. Spoon half of the Chimichurri sauce over the meat.
When ready to make the sandwich, cut baguette in half lengthwise. Spread 2 tablespoon Chimichurri sauce at the bottom piece. Place 4-5 slices of the meat and top it off with tomatoes, if you like.
