Instructions
1. Marinate the Steak
In a bowl, whisk together olive oil, lime juice, orange juice, lime zest and all spices. Place the steak in a shallow dish or bag and coat well with the marinade. Marinate for at least 30 minutes (up to 4 hours for deeper flavor).
2. Cook the Steak
Heat a skillet or grill pan over medium-high heat. Cook the steak for about 4–5 minutes per side, depending on thickness and desired doneness. Transfer to a cutting board, rest for 5 minutes, then slice thinly against the grain.
3. Sauté the Vegetables
In the same pan, heat olive oil over medium heat. Add peppers and onion, season with salt, pepper and garlic powder. Cook 5–7 minutes until softened and lightly caramelized.
4. Assemble the Quesadillas
Heat a clean skillet over medium heat and melt a little butter. Place one tortilla in the pan, sprinkle with cheese, add steak slices and vegetables, then top with more cheese. Cover with another tortilla.
5. Cook Until Crispy
Cook 2–3 minutes per side, pressing gently, until tortillas are golden brown and cheese is fully melted. Repeat with remaining tortillas.
6. Slice & Serve
Cut each quesadilla into wedges and serve hot with sour cream, guacamole, salsa and fresh cilantro.
You Must Know (Helpful Tips)

- A cast-iron skillet gives the best golden crust
Storage & Reheating
