How to Make It
Preheat oven to 450°.
Place squash in a large microwave-safe dish; add water to a depth of 1/2 inch. Cover with plastic wrap; microwave at HIGH 5 minutes. Drain and toss squash with 1/8 teaspoon kosher salt.
While squash cooks, place pizza crust on a baking sheet; spread alfredo sauce over crust.
Heat oil in a nonstick skillet. Add spinach; sauté 1 minute. Stir in remaining 1/8 teaspoon salt. Arrange wilted spinach over sauce. Top with squash and goat cheese; sprinkle with pepper.
Bake pizza in bottom third of oven at 450° for 6 minutes. Turn oven to broil; cook pizza 1 additional minute or until crust is crispy. Cut pizza into 8 wedges, and serve immediately.
