Preheat oven to 425 degrees. In a small bowl, combine olive oil, garlic powder, and dried oregano until well blended. Brush seasoned olive oil mixture over the rim of the crust only (about an inch).
Brush pizza sauce evenly over the center of the crust, leaving off about an inch of seasoned rim. Sprinkle minced garlic over the sauce, then top with half of the shredded Mozzarella cheese.
Sprinkle sun-dried tomatoes over the shredded cheese. Spread the spinach evenly over the tomatoes and shredded cheese. Top with pieces of chicken, then top with remaining half of shredded Mozzarella cheese. Sprinkle with pine nuts.
Carefully, place the pizza on the middle rack of the oven. Bake for 12 to 15 minutes, or until cheese has melted and crust is crispy.
Notes
Crust Variations: For a softer crust, place pizza on a baking sheet or pizza pan and bake at 375 degrees for 20-25 minutes, or until cheese is melted.
