In a small bowl, combine the seasonings for the chicken: gochugaru, garlic powder (or finely minced garlic), black pepper, sesame oil, and sesame seeds.
Add in the chicken and toss to combine.
Heat up a large frying pan or skillet over medium heat.
Place a tortilla onto the pan.
Sprinkle on some Monterey Jack cheese onto the tortilla and layer on the seasoned chicken.
Add the kimchi over the top and sprinkle on more cheese.
Place a 2nd tortilla on top and press firmly with a spatula.
Cook over medium-low heat until the tortilla is slightly crisp and golden brown, about 3-4 minutes.
Carefully flip the quesadilla with a spatula and cook for another few minutes until the cheese is completely melted.
Remove from the pan and place onto a cutting board.
Cut into wedges, garnish with additional sesame seeds, chopped green onions and cilantro and serve with gochujang sour cream (recipe below).
Make the gochujang sour cream:
In a bowl, combine 1 tablespoon gochujang with 1-2 teaspoon hot water and mix until smooth.
Stir in ¼ teaspoon granulated sugar or honey.
Mix in the sour cream and stir until combined.
Serve with the Kimchi Chicken Quesadillas.
Notes
