Ingredients

  • For the Marinade & Steak:
    • 1 flank steak (1.52 pounds)
    • ⅓ cup olive oil
    • 3 tablespoons tamari or soy sauce
    • Juice of 1 lime
    • Juice of 1 orange
    • 1 tablespoon balsamic vinegar
    • 3 garlic cloves, minced
    • 1 tablespoon fresh rosemary, chopped
    • 1 tablespoon fresh thyme, chopped
    • 1 teaspoon ground cumin
    • Salt and freshly ground black pepper, to taste
  • For the Mango Avocado Salsa:
    • 1 ripe mango, peeled and diced
    • 1 ripe avocado, diced
    • ½ red onion, finely chopped
    • 1 jalapeño, seeded and minced (optional)
    • Juice of 1 lime
    • ¼ cup fresh cilantro, chopped
    • Salt and pepper, to taste

Instructions

  1. Make Marinade: In a medium bowl or resealable bag, whisk together olive oil, tamari, lime juice, orange juice, balsamic vinegar, garlic, rosemary, thyme, cumin, salt, and pepper.
  2. Marinate Steak: Add flank steak and coat fully. Refrigerate 2–6 hours, turning occasionally.
  3. Preheat Grill: Heat grill or grill pan to medium-high. Remove steak from marinade; let excess drip off. If desired, boil reserved marinade for basting.
  4. Grill Steak: Cook steak 4–6 minutes per side, basting with reserved marinade or olive oil/herbs if desired.
  5. Rest Steak: Transfer to cutting board; let rest 5–10 minutes. Slice thinly against the grain.
  6. Make Salsa: Combine mango, avocado, red onion, jalapeño, lime juice, cilantro, salt, and pepper. Mix gently.
  7. Serve: Top sliced steak with mango avocado salsa and enjoy.

Notes

  • Skirt steak or sirloin can replace flank steak.
  • Add cucumber or cherry tomatoes to salsa for extra crunch.
  • For smoky flavor, add smoked paprika or chipotle powder to marinade.
  • For less heat, omit jalapeño.
