Sauté the Vegetables:
Heat olive oil in a pan over medium heat. Sauté diced bell peppers, zucchini, mushrooms, and onions until soft (about 5-7 minutes). Add garlic powder, Italian seasoning, salt, and pepper. Remove from heat and cool slightly.

Prepare the Cheese Filling:
In a bowl, mix together shredded mozzarella cheese and softened cream cheese. Add salt and pepper to taste. Stir until smooth.

Roll Out the Dough:
Roll the puff pastry or pizza dough on a floured surface to your desired thickness. Cut dough into rectangles or squares (about 4-6 pieces per sheet).

Assemble the Rolls:
Place a spoonful of the cheese mixture on each dough piece, followed by a spoonful of sautéed vegetables. Be careful not to overstuff.

Roll and Seal:
Fold the dough over the filling and pinch the seams to seal the rolls tightly.

Bake the Rolls:
Preheat oven to 375°F (190°C). Place rolls on a parchment-lined baking sheet. Lightly brush the tops with olive oil or melted butter. Bake for 15-20 minutes until golden brown and puffed.

Garnish and Serve:
Let rolls cool slightly before serving. Garnish with fresh parsley if desired. Serve warm and enjoy!
