Preheat your Traeger Flatrock or Blackstone grill, or any flat surface indoor or outdoor griddle you use to medium to medium-high temperature. Add cooking oil to coat the griddle. Once the oil is hot and shiny, add the already whipped quesadilla. In a large resealable bag, mix chicken thighs, olive oil, kosher salt, black pepper, Blackstone Tequila and lime seasoning, Blackstone taco and fajita seasoning, Herdez green sauce, and lime juice.
Blackstone chicken fajita quesadillas are incredibly delicious and easy to prepare because they are all made on the Blackstone griddle.
