Slice the chicken breast into thin strips.
In a bowl, combine lime juice, neutral oil, paprika, chili powder, cumin, oregano, onion powder, garlic powder, salt, and black pepper. Add the chicken and mix well to coat. Let marinate for about 10–15 minutes if time allows.
Slice the green bell pepper, red bell pepper, and onion into thin strips.
Heat a large skillet over medium-high heat. Add a drizzle of oil.
Add the marinated chicken to the hot skillet and cook until browned and fully cooked through, about 6–8 minutes. Remove the chicken from the pan and set aside.
In the same skillet, add the sliced peppers and onions. Cook until slightly softened and lightly caramelized, about 4–5 minutes.
Return the cooked chicken to the skillet and toss everything together until heated through.
Serve the chicken and vegetables in warm tortillas or pita bread. Top with feta cheese or sour cream if desired.
