Ingredients

Scale
  • 1 lb flank steak or chicken breast, thinly sliced
  • 2 tbsp olive oil
  • 2 cloves garlic, minced
  • 1 tsp ground cumin
  • 1 tsp smoked paprika
  • 1/2 tsp chili powder
  • Juice of 1 lime (about 2 tbsp)
  • Salt and freshly ground black pepper, to taste
  • 1 large red bell pepper, thinly sliced
  • 1 large green bell pepper, thinly sliced
  • 1 medium yellow onion, thinly sliced
  • Warm flour or corn tortillas (for serving, optional)
  • Fresh cilantro, chopped (optional)
  • Sour cream or Greek yogurt (optional)
  • Sliced avocado or guacamole (optional)
  • Shredded cheese (cheddar or Monterey Jack, optional)

Instructions

  1. In a large mixing bowl, combine olive oil, minced garlic, ground cumin, smoked paprika, chili powder, lime juice, salt, and pepper. Whisk until well blended.
  2. Add the thinly sliced flank steak or chicken strips to the marinade and toss to coat evenly. Let marinate for at least 15 minutes (minimum 5 minutes if short on time).
  3. While the meat marinates, thinly slice the red and green bell peppers and the yellow onion into uniform 1/4 inch slices.
  4. Tear off two large sheets of heavy-duty aluminum foil (about 18 inches long each). Divide the marinated meat and sliced vegetables evenly between the two sheets, placing them in the center.
  5. Fold the foil over the ingredients and crimp the edges tightly to seal packets completely, preventing steam from escaping during cooking.
  6. Place the foil packets on hot campfire coals or a grill grate set over the fire. Cook for about 8-10 minutes per side, flipping once halfway through, for a total of 15-20 minutes. Ensure meat is cooked through (165°F/74°C for chicken, medium rare to medium for steak).
  7. Carefully open one packet to check if the meat and vegetables are tender and juicy. Be cautious of hot steam escaping. If needed, reseal and cook a few minutes longer.
  8. Serve immediately with warm tortillas and your favorite toppings such as cilantro, sour cream, avocado, or shredded cheese.

Notes

Marinate meat for 15-30 minutes for best flavor but avoid over-marinating to prevent mushy texture. Use thin slices of meat and vegetables for even cooking. Double wrap foil packets or place on a baking sheet to prevent bursting. Can be cooked in a 400°F (200°C) oven for about 20 minutes if no campfire is available. Use corn or gluten-free tortillas for gluten-free diet. Omit sour cream or use plant-based alternatives for dairy-free option.
