Preheat oven to 450 degrees F.
Lightly spray the backside of a baking sheet with cooking spray. Unroll the pizza dough onto the sheet pan.
In a medium bowl, stir together pasta sauce, garlic powder, and oregano. Use a pastry brush to brush the top of the dough with olive oil. Spread the sauce over pizza dough leaving a 1/2-inch border. Top with goat cheese. Bake for 12 to 17 minutes.
In a large bowl combine the spinach with 2 tablespoons reserved artichoke marinade, artichoke hearts, red bell pepper strips, and olives. Toss together.
Remove pizza from the oven and top with veggies. Slice and serve.
