Steak & Marinade:
  • 2-3 Whole Flat Iron Steaks
  • 2 cups Soy Sauce
  • 2.5 tbsp Jalapeno Lime Pilsner Rub
  • 2.5 tbsp Chipotle Paste
  • 2 tbsp Chopped Cilantro
  • 3 medium Limes juiced
  • 2 Navel Oranges juiced
  • 1 tbsp Canola Oil
  • 4-6 Bell Peppers sliced
  • 1 Red Onion sliced
  • 2 tbsp Jalapeno Lime Pilsner Rub
  • 1 tbsp Canola Oil
  • Warm Tortillas
  • Cotija Cheese
  • Sour Cream
  • Cilantro
  • Lime Wedges
  1. In a large food safe bowl, add all the ingredients for the beef marinade and mix thoroughly. Add your steak into the marinade, mix, cover and place in the fridge for at least 4 hours but ideally overnight.
  2. Preheat your grill to medium-high temperature (about 350F) for direct cooking
  3. Add the steaks to the grill and cook for about 4-5 minutes per side until medium rare (about 120 internal). When the steaks are done, pull them off and let them rest for 12 minutes.
  4. Finally, add a cast iron skillet or plancha to the fire and heat up for 1 minute with oil. Drop your veggies into the skillet and season with Jalapeno Lime Pilsner seasoning or your favorite veggie seasoning. Cook until the veggies have softened (about 5 minutes) then pull them off and begin assembling.
  5. Slice your steak against the grain and serve it or chop into bites. Top your sizzling veggies with the sliced steak and garnish with cotija cheese, chopped cilantro and more lime juice. Serve with warm tortillas, more cheese, cilantro and limes. Enjoy!
