You can choose your preferred filling ingredients for the stromboli.
Activate yeast in warm water with sugar and oil, let it foam, then combine with flour and salt to form a smooth dough.
You can use your hand or a stand mixer for convenience.
Flatten your dough using a rolling pin into a 9x12 inch rectangle. Brush with a mixture of oil and crushed garlic.
Layer ingredients across the dough. Then carefully roll stromboli into a tight log from the long side.
Bake stromboli until golden brown. Let it cool for 15 minutes before slicing. Serve the slices with warmed marinara sauce for dipping.
