Instructions
Prepare the Chimichurri Sauce: In a bowl, mix the chopped parsley, minced garlic, olive oil, apple cider vinegar, dried oregano, red pepper flakes, salt, and pepper until well combined. Adjust seasoning to taste. Set aside to let the flavors meld.
Marinate the Steak: Rub the flank steak with 2 tablespoons of olive oil, salt, and pepper. Place it in a resealable bag, pour half of the chimichurri sauce over it (reserve the other half for serving), and let it marinate in the refrigerator for at least 30 minutes, or up to 2 hours for deeper flavor.
Cook the Steak: Preheat a grill or cast-iron skillet over medium-high heat. Remove the steak from the marinade and grill for about 4-5 minutes per side for medium-rare, or until your desired doneness. Once cooked, let it rest for 5-10 minutes before slicing.
Heat the Tortillas: While the steak is resting, warm the tortillas on the grill or in a skillet for about 30 seconds on each side until pliable.
Assemble the Tacos: Slice the rested steak against the grain into thin strips. Lay a few strips of steak on each tortilla. Top with halved cherry tomatoes, sliced avocado, and shredded lettuce. Drizzle with the reserved chimichurri sauce.
Serve: Serve the tacos immediately, garnished with extra parsley or lime wedges if desired.
Notes
Adjust the spiciness of the chimichurri sauce by varying the amount of red pepper flakes.
