Prepare the Sauce: In a saucepan, sauté Garlic in Olive Oil until fragrant. Add Crushed Tomatoes, Tomato Paste, Basil, Oregano, Red Pepper Flakes, Salt, and Pepper. Simmer for 15 minutes, stirring occasionally.
Stretch or roll out the Dough to your desired thickness and shape.
Brush the Dough with Olive Oil.
Spread the Sauce evenly over the Dough, leaving a small border for the crust.
Sprinkle the Mozzarella and Parmesan Cheese evenly over the Sauce.
Arrange the Green Bell Pepper, Red Onion, Black Olives, Pineapple, and Jalapenos (if using) evenly over the Cheese.
Bake for 12-15 minutes, or until the crust is golden brown and the Cheese is melted and bubbly.
