Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions and bell peppers, cooking until softened, about 5 minutes. Remove from the pan and set aside.
In the same skillet, add the remaining olive oil. Add the sliced chicken and season with garlic powder, salt, black pepper, smoked paprika, and Worcestershire sauce. Cook for 7-8 minutes, stirring occasionally, until fully cooked and slightly browned.
Return the sautéed onions and peppers to the skillet. Stir everything together, allowing the flavors to meld for 2 minutes.
Place the provolone slices on top of the chicken mixture. Cover the skillet and let the cheese melt for 1-2 minutes.
