Preheat the oven to 500. Preheat a pizza stone.
In a small bowl, combine the 1 tablespoon of olive oil with the minced garlic and let stand.
On a lightly floured work surface, roll out the dough to form a 12-inch round, 1/4 inch thick. Transfer the round to a lightly floured pizza peel.
Leaving a 1/2-inch border of dough, brush the round with the garlic oil and sprinkle with crushed red pepper, salt and black pepper.
Scatter the onion slices over the round; top with the mozzarella and savory.
Arrange the squash slices on top in a single layer, overlapping them slightly.
Dot with the crumbled goat cheese.
Slide the pizza onto the hot stone and bake for about 5 minutes, until the bottom is crisp and the squash is slightly browned. Transfer the pizza to a work surface.
Sprinkle with the walnuts and drizzle with olive oil. Cut into wedges and serve.
