In a large mixing bowl, combine the shredded chicken, both types of cheese, softened cream cheese, diced red and green bell peppers, chopped onion, and minced jalapeño (if using). Season the mixture with garlic powder, ground cumin, smoked paprika, and a sprinkle of salt and pepper. Stir well to ensure all ingredients are evenly distributed and the mixture is creamy.
Heat 1 tablespoon of olive oil in a large skillet over medium heat until shimmering.
Once the skillet is hot, lay one tortilla flat in the skillet, and evenly sprinkle half of the prepared chicken and cheese mixture over one half of the tortilla.
Gently fold the tortilla in half, covering the filling completely. Cook for 3-4 minutes, or until the bottom side is a beautiful golden brown and the cheese starts to melt.
Using a spatula, carefully flip the quesadilla over and cook for an additional 3-4 minutes on the other side, achieving a crispy, golden brown crust.
Once cooked, transfer the quesadilla to a cutting board and allow it to cool for a minute before slicing into wedges for easy serving.
Repeat the cooking process with the remaining tortillas and filling, adding the remaining olive oil to the skillet as necessary to prevent sticking.
Serve the quesadillas warm, garnished with fresh chopped cilantro, and offer sour cream or guacamole on the side for dipping pleasure.
Notes
Feel free to adjust the spice level by adding or omitting the jalapeño.
