01 - Heat olive oil in a large skillet over medium-high heat until shimmering.
02 - Add sliced chicken to the hot skillet, season with salt and black pepper, and cook for 5–6 minutes until golden brown and cooked through. Transfer to a plate and set aside.
03 - Add onions and bell peppers to the same skillet. Sauté for 6–8 minutes until softened and slightly caramelized, stirring occasionally.
04 - Stir in minced garlic, Worcestershire sauce, smoked paprika, and red pepper flakes. Cook for 1 minute until fragrant.
05 - Return chicken to the skillet, mixing thoroughly with the vegetables. Cook for 2 minutes until everything is heated through.
06 - Arrange provolone cheese slices evenly over the chicken and vegetable mixture. Cover the skillet and cook for about 2 minutes until cheese is fully melted.
07 - Serve hot directly from the skillet or spoon into hoagie rolls for a classic sandwich presentation.
