Begin by rolling out your pizza dough into a large square on a floured surface. Transfer it to a pizza stone or a baking sheet lined with parchment paper.
Preheat your oven to 475°F (245°C).
Drizzle 1 tablespoon of olive oil over the rolled-out pizza crust and evenly coat the surface.
Spread the pizza sauce evenly across the crust, leaving a small border around the edges. Sprinkle the shredded mozzarella cheese generously over the sauce.
Distribute the sliced garlic, spicy sausage, and sun-dried tomatoes evenly over the cheese. Sprinkle Italian seasoning over the top.
Place the pizza in the preheated oven and bake for 15-20 minutes, or until the crust is golden and the cheese is bubbling.
Once the pizza is out of the oven, let it cool for a minute. Top it with fresh arugula leaves, drizzling the remaining olive oil over the top.
Slice the pizza into squares or triangles, and serve hot.
