1. Preheat Oven:
   Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Prepare Filling:
   In a large bowl, combine the shredded chicken, cooked vegetables, cream cheese, mayonnaise, garlic powder, onion powder, salt, and pepper. Mix well until thoroughly combined.
3. Assemble Rolls:
   Unroll the crescent roll dough and separate it into triangles. Spoon a generous amount of the chicken mixture onto the wide end of each triangle. Sprinkle some cheddar and mozzarella cheese over the filling.
4. Roll and Arrange:
   Carefully roll up the triangles, starting from the wide end and rolling towards the point. Place each roll in the prepared baking dish, arranging them in a single layer.
5. Top with Cheese:
   Sprinkle the remaining cheddar and mozzarella cheese over the top of the crescent rolls. If using, sprinkle poppy seeds over the cheese.
6. Bake:
   Bake in the preheated oven for 20-25 minutes, or until the crescent rolls are golden brown and the cheese is melted and bubbly.
7. Garnish and Serve:
   Remove from the oven and let cool for a few minutes. Garnish with fresh thyme or parsley. Serve hot.
