Here are a few tips to keep your pizza rolls from leaking :1. Use a thicker pizza dough. This will help to prevent the filling from oozing out when you bite into the roll .2. Be generous with the cheese filling. The cheese acts as a barrier between the dough and the sauce, helping to keep everything in its place. 3. Use a good quality marinara sauce. A thicker, more robust sauce will also help to keep the filling from seeping out. 4. Make sure the rolls are well-sealed before baking. Once they're filled, use your fingers to press the edges of the dough together so that no filling can escape during baking. 5. Bake the pizza rolls until they're golden brown and crispy on the outside. This will help to further seal any fillings and prevent leakage.
