# How to Make It:

02 - Preheat a large skillet or grill pan over high heat. Add a small amount of oil if needed. Cook the marinated beef in a single layer for 2 to 3 minutes until just cooked through. Remove from pan and set aside.
03 - Using the same pan, add sliced bell peppers and onion. Sauté over medium-high heat for 4 to 5 minutes until vegetables soften and develop slight char at edges.
04 - Return the beef to the pan with the vegetables. Toss together for 1 to 2 minutes to combine flavors and heat thoroughly.
05 - Serve the sizzling beef and vegetables wrapped in warmed tortillas with optional toppings such as cheese, sour cream, avocado, cilantro, and lime wedges.

# Expert Tips:

01 -
  • Everything cooks in under 15 minutes once your beef is marinated, so weeknight chaos becomes weeknight victory.
  • The smoky char on the peppers and the tangy lime-soaked beef taste like restaurant fajitas without leaving your house.
  • You can pile on exactly what you want, whether thats extra cheese, a mountain of avocado, or just cilantro and a squeeze of lime.
02 -
  • Slice your beef against the grain, not with it, or youll end up chewing forever instead of enjoying tender, juicy strips.
  • Dont crowd the pan when searing the beef, overcrowding steams the meat instead of giving you that beautiful browned crust.
  • Heat your tortillas in a dry skillet or directly over a gas flame for a few seconds on each side, cold tortillas are sad tortillas.
03 -
  • Use a cast iron skillet if you have one, it gets screaming hot and holds the heat for perfect char marks.
  • Add a dash of hot sauce or sliced jalapeños to the marinade if you like your fajitas with a kick.
  • Let the beef rest for a minute after searing before slicing further, it keeps the juices inside instead of all over your cutting board.
