Instructions
Prepare the Chimichurri Sauce: In a medium mixing bowl, combine the finely chopped parsley, cilantro, minced garlic, and red pepper flakes. Pour in the olive oil and red wine vinegar. Season with salt and black pepper to your preference. Mix the ingredients thoroughly and allow the sauce to sit for at least 20 minutes at room temperature, which will enhance the flavors.
Prep the Steak: Rub the flank steak with 2 tablespoons of olive oil evenly on both sides, then sprinkle generously with salt and black pepper to enhance the flavor.
Cook the Steak: Preheat a grill or skillet over medium-high heat until very hot. Place the seasoned flank steak on the grill or in the skillet and cook for approximately 5-7 minutes on each side, or until it reaches your desired level of doneness (medium-rare is suggested for tenderness). Once cooked, remove the steak from the heat, cover it loosely with foil, and let it rest for 5 minutes to allow juices to redistribute.
Slice the Steak: After resting, use a sharp knife to slice the steak thinly against the grain. This cutting technique will ensure more tender pieces.
Warm the Tortillas: In a dry skillet over medium heat, warm the corn tortillas, flipping them after about 30 seconds on each side, until they are soft and pliable but not crispy.
Assemble the Tacos: Take a warm tortilla and place a few slices of the rested steak onto the center. Top it with halved cherry tomatoes, chopped red onion, avocado slices, and add a generous spoonful of the chimichurri sauce over the top.
Garnish and Serve: Finish your tacos by sprinkling fresh cilantro leaves for a burst of color and flavor. Serve immediately while hot.
Notes
Allow the chimichurri sauce to sit for at least 20 minutes to enhance flavors.
