In a medium bowl, combine the shredded chicken, ground cumin, chili powder, diced bell peppers, and red onion until well mixed.
Lightly brush one side of each tortilla with a small amount of olive oil using a pastry brush.
Place one tortilla, oiled-side down, in a large non-stick skillet over medium heat.
Spread one quarter of the chicken and vegetable mixture and one quarter of the cheese over one half of the tortilla.
Fold the tortilla in half to cover the filling, creating a semi-circle.
Cook for 2 to 3 minutes until the bottom is golden brown and crisp, then flip carefully and cook for an additional 2 minutes until the cheese is fully melted.
Repeat the process with the remaining tortillas and filling.
Remove from the skillet, allow to rest for one minute, then slice into three wedges and garnish with fresh cilantro.
