Mushroom, Zucchini, and Swiss-Cheese Pizza

• VEGETARIAN

Ingredients

1. 2 pounds store-bought or homemade pizza dough
2. 3 tablespoons olive oil
3. 1 zucchini, halved lengthwise and cut crosswise into thin slices
4. 1 pound mushrooms, sliced thin
5. 1 teaspoon salt
6. 1/2 teaspoon fresh-ground black pepper
7. 1 teaspoon dried thyme
8. 1/2 cup dry white wine
9. 1/2 pound Swiss cheese, grated (about 2 cups)
10. 1/4 cup grated Parmesan

1. Heat the oven to 425°. Oil two 12-inch pizza pans or large baking sheets. Press the dough into a 12-inch round, or 9-by-13-inch rectangle, on each prepared pan. Bake until the dough begins to brown, 10 to 15 minutes.
2. Meanwhile, in a large nonstick frying pan, heat 1 tablespoon of the oil over moderately high heat. Add the zucchini and cook, stirring occasionally, until almost tender, about 3 minutes. Transfer to a small bowl. Heat the remaining 2 tablespoons of oil in the same pan. Add the mushrooms, salt, pepper, and thyme and cook, stirring frequently, until the mushrooms are golden, about 5 minutes.
3. Return the zucchini to the pan, add the wine, and simmer, stirring occasionally, until the vegetables are tender and all the wine has evaporated, about 5 minutes more.
4. Spread the vegetable mixture on the partially baked pizza crusts. Sprinkle each with Swiss cheese and Parmesan and bake until the cheese melts, about 10 minutes.
