  • 1 lb beef Flank Steak
  • 2 cups Cherry tomatoes or 2 large heirloom tomatoes, halved
  • 4 ears Corn or 2 cups kernels
  • ½ Red onion, diced
  • 2 tablespoon Avocado oil
  • Salt and pepper, to taste for vegetables
  • Tortillas, for serving

Chimichurri Sauce

  • 1 cup packed fresh parsley
  • 1 cup packed fresh cilantro
  • 2 cloves garlic can sub with 1 teaspoon dried garlic
  • ¼ cup red wine vinegar
  • ½ cup olive oil
  • ¾-1 teaspoon salt
  • ½ teaspoon chili flakes optional


  • In a food processor or blender, add all chimichurri ingredients. Process until well combined and desired consistency reached. Reserve ½ of the sauce and refrigerate for serving.
  • Place Flank Steak in a glass baking dish. Pour remaining marinade over the top and rub marinade over the entire surface. Flip steak and repeat. Marinate steaks for at least 30-60 minutes, flipping once.
  • Remove steak from marinade and lightly pat with paper towels to remove excess liquid. Grill steak, covered, for 7 to 11 minutes for medium rare (145°F) doneness, turning once. During the last 5-6 minutes, add the tomatoes and corn to the grill. Cook, flipping once, until slightly tender and golden.
  • Let steak rest for 5-10 minutes. Carve steak lengthwise in half, then crosswise, against the grain, into thin slices. Top tortillas evenly with steak slices and vegtables. Drizzle with additional Chimichurri and sprinkle with leftover cilantro.
