Ingredients
  

For the Chili Lime Steak Marinade:

  • 2 tbsp olive oil
  • 2 tbsp fresh lime juice
  • 2 tbsp fresh orange juice
  • 1 tbsp lime zest
  • 2 tsp chili powder
  • 2 tsp ancho chili powder
  • 1 tsp smoked paprika
  • 1 tsp garlic powder
  • ½ tsp cumin
  • ½ tsp salt
  • ¼ tsp black pepper
  • 1 tsp red pepper flakes optional, for heat

For the Fajita Veggies:

  • 1 red bell pepper sliced
  • 1 green bell pepper sliced
  • 1 yellow onion sliced
  • 2 Fresno peppers chopped
  • 1 tbsp olive oil
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp garlic powder
  • For the Quesadillas:
  • 4 large flour tortillas
  • 2 cups shredded Mexican blend cheese or cheddar, Monterey Jack
  • 1 tbsp butter for crisping tortillas

Optional Toppings:

  • Sour cream
  • Guacamole
  • Salsa
  • Fresh cilantro

Instructions
 

  • Step 1: Marinate the Steak
  • In a small bowl, whisk together olive oil, lime juice, lime zest, and all the spices. Place the steak in a shallow dish or zip-top bag, then pour the marinade over it. Let it marinate for at least 30 minutes (or up to 4 hours for deeper flavor).
  • Step 2: Cook the Steak
  • Heat a large skillet or grill pan over medium-high heat. Cook the steak for 4-5 minutes per side (for medium-rare) or longer for desired doneness. Remove from heat and let it rest for 5 minutes, then slice it thinly against the grain.
  • Step 3: Sauté the Fajita Veggies
  • In the same pan, add 1 tbsp olive oil over medium heat. Add bell peppers and onions, season with salt, black pepper, and garlic powder. Sauté for 5-7 minutes until softened and slightly caramelized.
  • Step 4: Assemble the Quesadillas
  • Heat a clean skillet over medium heat and melt a little butter. Place a tortilla in the skillet, then layer on cheese, steak slices, and fajita veggies. Top with another sprinkle of cheese and place a second tortilla on top. Cook for 2-3 minutes per side, pressing lightly, until golden and crispy.
  • Step 5: Serve & Enjoy!
  • Slice into quarters and serve with your favorite toppings like guacamole, sour cream, or salsa. Enjoy these cheesy, crispy, flavor-packed quesadillas with a side of Mexican rice or a fresh salad!
