Heat olive oil in a large skillet over medium-high heat. Once hot, add the sliced bell peppers and onion.
Cook for 5–6 minutes, stirring occasionally, until the vegetables soften and start to develop light charred edges. This caramelization enhances their sweetness and depth of flavor.
Season the vegetables with garlic powder, chili powder, salt, and black pepper. Stir well to evenly coat. Remove the mixture from the skillet and set aside.
Step 2: Warm the Chicken
In the same skillet, add the cooked chicken. Stir frequently for 2–3 minutes until heated through and slightly golden at the edges. This step helps the chicken absorb the flavorful remnants from the vegetables.
Step 3: Add Ranch and Cheese
Turn off the heat. Stir in the ranch dressing and shredded cheese while the skillet is still warm.
Mix until the cheese begins to melt and the chicken and vegetables are coated in a creamy, flavorful sauce. The residual heat should be enough to achieve a smooth, velvety consistency without overcooking the filling.
