Creating your Cheesy Steak Quesadilla with Chipotle Lime Sauce is easy if you follow these steps:

1. Prepare the Steak: Heat olive oil in a skillet over medium-high heat. Season the sliced steak with taco seasoning, salt, and pepper. Cook for 4-5 minutes until browned and cooked through. Remove from heat and set aside.

2. Make the Chipotle Lime Sauce: In a small bowl, combine sour cream, lime juice, chipotle in adobo, and salt. Mix until smooth. Adjust seasoning to taste and set aside.

3. Assemble the Quesadillas: On half of each tortilla, layer a generous portion of shredded cheese followed by the cooked steak. Top with additional cheese if desired, then fold the tortillas in half.

4. Cook the Quesadillas: Wipe the skillet clean and return it to medium heat. Place a folded quesadilla in the skillet and cook for 3-4 minutes on each side, until the tortillas are golden brown and the cheese has melted.

5. Remove and Slice: Once cooked, remove the quesadilla from the skillet and let it rest for a minute. Slice into wedges using a sharp knife.

6. Repeat: Repeat the cooking process for any remaining quesadillas until all ingredients are used.

7. Serve: Serve the quesadillas hot, drizzling them with the chipotle lime sauce and garnishing with avocado slices and chopped cilantro if desired.
