02 - Add sliced chicken, season with salt and black pepper, and cook for 5-6 minutes until golden and just cooked through. Transfer chicken to a plate and set aside.
03 - In the same skillet, add onions and bell peppers. Sauté for 6-8 minutes until softened and slightly caramelized.
04 - Stir in minced garlic, Worcestershire sauce, smoked paprika, and red pepper flakes. Cook for 1 minute until fragrant.
