In a bowl whisk together 1/4 cup olive oil, rosemary, white wine vinegar and kosher salt. Place the chicken in the marinade and turn a couple times to coat. Cover and refrigerate for at least 2 hours.
After two hours, slice chicken into bite size pieces and cook over medium heat until cooked through.
Meanwhile, preheat the oven to 350 degrees. And lay your prepared pizza dough out onto a pizza pan.
In another pan heat remaining olive oil over medium heat. Add garlic and cook just until fragrant, about 30 seconds. Brush onto pizza dough.
Layer pizza dough with 1/2 cup mozzarella, spinach, chicken and sun dried tomatoes. Sprinkle top with Parmesan and remaining mozzarella. Bake 20 - 30 minutes or until cheese is bubbly and crust is golden. Serve hot.
