In a large bowl, combine the shredded chicken, chipotle sauce, cumin, and garlic powder. Mix until the chicken is well coated with the sauce and spices.
Stir in the black beans, corn, and chopped cilantro into the chicken mixture until evenly combined.
Heat a skillet over medium heat and add a small amount of cooking oil.
Place one tortilla in the skillet. Sprinkle half of the cheese evenly over the tortilla.
Spread half of the chicken mixture over the cheese, then sprinkle the remaining cheese on top.
Fold the tortilla in half and cook until the bottom is golden brown and the cheese has melted, about 3-4 minutes.
Carefully flip the quesadilla and cook the other side until golden brown, about another 3-4 minutes.
Remove from the skillet and let it cool for a minute before slicing into wedges.
Repeat the steps with the remaining tortillas and filling mixture.
Serve warm with avocado slices, sour cream, and salsa on the side.
Notes
Arrange the quesadilla wedges on a large plate, drizzling with extra chipotle sauce, and add a garnish of cilantro and lime wedges for a fresh touch.
