  • 2 pounds sirloin steak, sliced into thin strips
  • 3 tablespoons taco seasoning, divided (one package of taco seasoning is about 3 tablespoons)
  • 1 tablespoons vegetable or olive oil
  • 3 one each of a red, yellow, and greed bell pepper, sliced thin strips
  • 1 medium onion, sliced
  • 1 lime, juiced
  • optional toppings like: tortilla shells, shredded cheese, guacamole, salsa, sour cream, etc.


  • Preheat your grill. Cut six 12 to 18 inch rectangle pieces of heavy-duty aluminum foil. Spray the foil with nonstick cooking spray.
  • In a medium bowl, season the steak strips with 2 tablespoons of the taco seasoning and the juice of one lime. Mix to coat. Divide the meat equally among the 6 pieces of aluminum foil.
  • In another medium bowl, add the vegetables, the remaining one tablespoon taco seasoning and one tablespoon vegetable oil; toss to coat. Divide equally among the 6 pieces of aluminum foil with the steak.
  • To fold the pockets, bring the long sides of the aluminum foil to meet over the beef. Fold the ends of the aluminum foil together, folding twice to create a seam. Roll up the shorter ends of the aluminum foil at least twice to create a sealed pocket.
  • Place the steak packets on the grill and cover the grill. Cook for 8 to 10 minutes, rotating the packets halfway if needed so they each cook evenly.
  • Remove the packets from the grill and carefully open to add additional toppings as desired or serve on warm tortillas.
