Marinate the Steak: In a bowl, combine olive oil, chili powder, cumin, garlic powder, salt, and pepper. Coat the steak in the mixture and let it marinate while you prep the veggies.

Prep the Veggies: Slice your bell peppers and onion into thin strips.

Heat the Skillet: In a large skillet over medium-high heat, add a splash of olive oil. As the oil shimmers, add the marinated steak.

Sear the Steak: Cook for 3–4 minutes on each side for medium-rare, until nicely charred.

Remove and Rest: Transfer the cooked steak to a plate and let it rest for a few minutes. Turn down the heat and add the veggies to the skillet, sautéing until tender and caramelized, about 5-7 minutes.

Slice the Steak: Once rested, cut the steak against the grain into thin strips.

Combine: Add the steak back to the skillet with the veggies, tossing everything together to warm through.

Serve: Lay out the tortillas and let everyone make their own fajitas, loading them with their favorite toppings.
