butternut squash—peeled, seeded, and sliced 1/4 inch thick
red onion, thinly sliced
fresh thyme leaves
kosher salt and black pepper
grated extra-sharp Cheddar (6 ounces)
arugula, thick stems discarded (about 4 cups)

- In a large bowl, toss the squash, onion, pine nuts, thyme, 1 tablespoon of the oil, ½ teaspoon salt, and ¼ teaspoon pepper.
- Scatter over the dough and sprinkle with the cheese. Bake until golden brown and crisp, 20 to 25 minutes.
