Step 1: Marinate the Steak
- In a medium bowl, whisk together olive oil, lime juice, soy sauce, Worcestershire sauce, garlic, cumin, chili powder, smoked paprika, salt, and pepper.

- Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, or overnight for enhanced flavor.
Step 2: Cook the Steak

- Remove steak from the marinade, letting excess drip off.

- Transfer to a plate and loosely cover with foil to rest.
Step 3: Sauté the Vegetables
- In the same skillet or pan, add a touch more olive oil if necessary.
- Add the bell peppers and onions.
- Cook for 5–7 minutes, stirring occasionally, until vegetables are soft and slightly caramelized.
Step 4: Assemble the Fajitas

 Pro Tips for Perfect Fajitas
- Slice Steak Thinly and Against the Grain: This ensures tenderness and easier chewing.
- Marinate Overnight: For maximum flavor, marinate the steak overnight in the fridge.
- Use High Heat: Cooking steak and veggies over high heat sears them quickly and locks in flavor.
- Don’t Crowd the Pan: If cooking in a skillet, work in batches to avoid steaming instead of searing.
- Warm Your Tortillas: A few seconds in a skillet brings out the best flavor and texture.
- Customize It: Add grilled mushrooms, jalapeños, or even pineapple for a sweet twist.
- Use a Cast Iron Skillet: For that restaurant-style sizzle and char.
 Fajita Variations
- Chicken Fajitas: Swap steak for boneless chicken thighs or breasts.
- Vegetarian: Use portobello mushrooms, tofu, or tempeh.
- Low-Carb: Serve over a salad or in lettuce wraps instead of tortillas.
- Spicy: Add sliced jalapeños to the veggie mix or hot sauce to the marinade.
 Serving Suggestions

- Refried Beans or Black Beans
- Grilled Corn or Elote (Mexican Street Corn)
- Tortilla Chips with Guacamole or Salsa Verde
