Preheat the Oven: Preheat your oven to 475°F (245°C). If using a pizza stone, place it in the oven while it preheats to ensure it gets hot.
Prepare the Chimichurri Sauce: In a small bowl, combine chopped parsley, minced garlic, red wine vinegar, olive oil, oregano, and red pepper flakes (if using). Stir well to combine. Season with salt and pepper to taste. Let the sauce sit for about 10-15 minutes to allow the flavors to meld together.
Roll Out the Pizza Dough: On a lightly floured surface, roll out your pizza dough into a round or rectangular shape, depending on your preference. Make sure it’s evenly rolled for a crispy texture. If you're using a pizza stone, transfer the dough onto a parchment paper or lightly floured pizza peel.
Spread the Chimichurri Sauce: Brush a thin layer of chimichurri sauce over the pizza dough, leaving a small border around the edges for the crust.
Add Toppings: Arrange the sweet tomato slices evenly across the pizza. Sprinkle the mozzarella cheese over the tomatoes, ensuring an even distribution. If desired, add grated Parmesan for an extra layer of flavor.
Bake the Pizza: Place the pizza into the preheated oven (on the pizza stone or baking sheet) and bake for 10-15 minutes, or until the crust is golden brown and crispy, and the cheese has melted and bubbled.
Finish and Serve: Once baked, remove the pizza from the oven. Allow it to cool for a couple of minutes before slicing. Optionally, drizzle a bit more chimichurri sauce over the top before serving for added freshness.
