For the Marinade:
-

Let’s Make it together
Marinate the Beef: In a bowl, combine olive oil, lime juice, garlic powder, cumin, and fajita seasoning. Add flank steak and coat well. Marinate for at least 30 minutes.
Sauté the Veggies: Heat a large skillet over medium-high heat. Add sliced bell peppers and onions. Sauté until they soften and turn slightly charred for about 5-7 minutes.
Cook the Beef: Remove veggies from the skillet. In the same skillet over high heat, add marinated flank steak. Cook until browned on both sides—about 3-4 minutes per side for medium-rare.
Rest & Slice the Meat: Once cooked to your liking, remove flank steak from heat and let it rest for 5 minutes. This helps retain juices; then slice against the grain into thin strips.
Toss Everything Together : Return sliced beef to the skillet with sautéed veggies. Stir everything together briefly over low heat until warmed through—just enough to mingle flavors!
Serve & Enjoy!: Warm your tortillas in another pan or microwave. Fill each tortilla with your beef-vegetable mix. Top with fresh cilantro or avocado if desired!
Now you have scrumptious beef fajitas ready to impress your family or friends! Remember to have some salsa or guacamole handy because let’s be honest—what’s a taco party without those?
