Ingredients
  

Protein

  • 1 lb flank steak, thinly sliced against the grain

Vegetables

  • 2 pieces bell peppers, sliced (mixed colors)
  • 1 medium onion, sliced

Oil & Seasoning

  • 2 tablespoons olive oil
  • 2 tablespoons fajita seasoning

Tortillas & Toppings

  • Tortillas (flour or corn)
  • Optional toppings: sour cream, salsa, guacamole, shredded cheese, lime wedges

Instructions
 

Preparation

  • Preheat your Blackstone griddle over medium-high heat.
  • In a bowl, combine the sliced flank steak, bell peppers, onion, olive oil, and fajita seasoning. Toss to coat evenly.

Cooking

  • Once the griddle is hot, add a little oil and spread the steak and veggies in an even layer.
  • Cook for about 5–7 minutes, stirring occasionally until the steak is cooked through and the vegetables are soft.
  • For extra char, push everything to the hot side for 30–60 seconds to caramelize.
  • Serve immediately with warm tortillas and your choice of toppings.
  • Slice any larger steak pieces thinly across the grain, squeeze fresh lime over the top, and enjoy.

Notes

Slice against the grain for tender steak. Don’t overcrowd the griddle for better caramelization. Use high heat and let the steak rest before slicing.
