Creating Cheesy Baked Vegetable Rolls is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
2. Prepare the Filling: In a large bowl, combine the chopped vegetables, mozzarella cheese, cheddar cheese, cream cheese, Parmesan cheese, olive oil, garlic powder, onion powder, salt, and pepper. Mix well until all ingredients are combined.
3. Prepare the Wrappers: If using phyllo dough, lay out one sheet and brush it lightly with melted butter or spray with cooking spray. Place another sheet on top and repeat the process.
4. Fill the Wrappers: Spoon a portion of the filling onto one end of the dough. Fold the sides over the filling and roll it up tightly. Ensure the ends are sealed to prevent the filling from escaping.
5. Place on Baking Sheet: Arrange the rolls on the prepared baking sheet seam side down. Brush the tops lightly with melted butter or cooking spray for a golden finish.
6. Bake: Bake in the preheated oven for 25-30 minutes, or until the rolls are golden brown and crispy.
7. Cool: Remove from the oven and let them cool for 5-10 minutes before serving.

These steps will guide you in creating these incredible rolls effortlessly.
