Preheat oven to 450 degrees F. Coat a baking sheet with cooking spray.
Place the potato slices in a saucepan
and cover with water. Bring to a boil; then lower the heat to a simmer
and cook until tender. Drain
well and pat dry with paper towels. (Potatoes
MUST be dry otherwise they will wet the pizza shell.)
Place the pizza
shell onto the greased baking sheet and cover lightly with tomato sauce. Arrange the potatoes uniformly around the pizza and sprinkle with sauteed
onions, chopped basil, rosemary, cheese, crushed red pepper and kalamata olives
. Bake at 450 degrees F for 15 minutes or until lightly browned. Cut into 8 wedges and serve.
