Finely dice the red bell pepper and yellow onion.
Heat a non-stick skillet over medium heat and add the olive oil.
Sauté the peppers and onions for 3-4 minutes until they are softened and slightly caramelized.
Add the shredded chicken breast to the skillet along with the sea salt, black pepper, garlic powder, and smoked paprika.
Stir the mixture for 2 minutes to ensure the chicken is heated through and well-coated in the spices.
Remove the chicken and vegetable mixture from the skillet and set aside.
Wipe the skillet clean and return it to medium heat.
Place the tortilla in the pan and spread the chicken mixture over one half of the tortilla.
Sprinkle the shredded cheddar cheese evenly over the chicken filling and fold the empty half of the tortilla over the top.
Cook for 2-3 minutes per side, pressing down gently with a spatula, until the tortilla is golden brown and the cheese is fully melted.
Transfer to a cutting board, let rest for one minute, then slice into three wedges and serve.
