Here's a traditional Mexican main dish prepared with a twist! The fruity salsa cools off the spicy pesto, and in my opinion, definitely makes the dish. Try it on chicken or pork, too. —Steve Meredith, Streamwood, Illinois

  • 1 medium onion, chopped
  • 1/4 cup lime juice
  • 2 tablespoons lemon-pepper seasoning
  • 2 tablespoons minced fresh cilantro
  • 2 garlic cloves, minced
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 beef flank steak (1 to 2 pounds)
  • 1 cup fresh cilantro leaves
  • 1 habanero pepper
  • 1 garlic clove
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 3 tablespoons olive oil
  • SALSA:
  • 1 medium mango, peeled and halved
  • 2/3 pound fresh pineapple, cut into 3 spears
  • 2 medium ripe avocados, peeled pitted and halved
  • 1 medium red onion, chopped
  • 8 corn tortillas (6 inches)


  1. In a shallow dish, combine the first seven ingredients. Add the steak and turn to coat. Cover; refrigerate for 6 hours or overnight.
  2. Place the cilantro, habanero, garlic, salt and pepper in a small food processor; cover and pulse until chopped. While processing, gradually add oil in a steady stream.
  3. For salsa, grill the mango, pineapple and avocado, covered, over medium heat for 2-3 minutes on each side or until tender; set aside.
  4. Drain and discard marinade from steak. Lightly oil the grill rack. Grill steak, covered, over medium heat for 6-8 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°). Let stand for 10 minutes.
  5. Place onion in a small bowl. Chop the grilled fruit and avocado; add to bowl. Grill tortillas, uncovered, over medium heat for about 1 minute on each side or until warm.
  6. Thinly slice beef across the grain; place on tortillas. Top with salsa and pesto.
