Cut chicken breast into strips and season with smoked paprika, salt, and pepper, then sear in oil in a large skillet over medium-high heat for 8 minutes until cooked through.
Drain and rinse the black beans, then add them to the skillet along with diced bell pepper and cook for 3 minutes until heated through.
Warm tortillas in a dry skillet or directly over a flame for 30 seconds per side.
Fill each tortilla with chicken and black bean mixture, then top with fresh cilantro and a squeeze of lime juice.
Serve immediately with lime wedges.
