Creating Broccoli Cheddar Chicken Rollups is straightforward if you follow these steps:

1. Preheat the Oven: Set your oven to 375°F (190°C) and prepare a baking dish by greasing it lightly.
2. Prepare the Filling: In a mixing bowl, combine the chopped broccoli, cheddar cheese, cream cheese, garlic powder, onion powder, salt, and black pepper. Mix until well combined.
3. Flatten the Chicken: Place one chicken breast between two pieces of plastic wrap. Use a meat mallet or rolling pin to gently pound the chicken until it’s about ½ inch thick. Repeat with the remaining chicken breasts.
4. Fill the Chicken: Spoon a portion of the broccoli and cheese mixture onto each flattened chicken breast. Roll the chicken tightly around the filling, securing it with toothpicks if necessary.
5. Prepare the Coating: In a shallow dish, combine the breadcrumbs and grated Parmesan cheese. Dip each chicken rollup in olive oil, then coat with the breadcrumb mixture, ensuring an even layer.
6. Place in Baking Dish: Arrange the coated rollups in the prepared baking dish, seam side down.
7. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and the coating is golden brown.
8. Rest: Once baked, remove the rollups from the oven and let them rest for about 5 minutes before serving.
9. Garnish: Sprinkle freshly chopped parsley over the rollups for a pop of color and added freshness.

Following these steps will ensure that your Broccoli Cheddar Chicken Rollups turn out perfectly every time!
