Prepare the Dough:

1. Mix warm water and yeast in a small bowl; let sit for 5 minutes until foamy.
2. Combine flour, sugar, and salt in a large bowl. Add yeast mixture and olive oil; mix until dough forms.
3. Knead dough on a floured surface for 8–10 minutes until smooth.
4. Cover with a damp cloth and let rise in a warm place for 1 hour.

Cook the Filling:

1. Heat a skillet over medium heat; cook ground beef or sausage until browned. Drain excess fat.
2. Stir in pizza sauce; cook for an additional 5 minutes. Set aside to cool slightly.

Assemble the Pizza Pie:

1. Preheat oven to 375°F (190°C).
2. Roll out dough into a 12–14 inch circle. Press into a greased deep baking or springform pan, covering the bottom and sides. Trim excess dough.
3. Layer shredded mozzarella on the crust base, followed by meat filling, mushrooms, bell peppers, and additional cheese. Repeat layers if desired.
4. Top with extra mozzarella and arrange pepperoni slices or other garnishes.

Bake to Perfection:

1. Bake for 25–30 minutes, or until the crust is golden brown and the cheese is bubbly.
2. Let cool slightly before slicing.

Serve and Enjoy:

• Slice into generous portions and serve warm. Pair with a fresh salad or garlic bread for a complete meal.
