Think of this tart as an homage to students’ penchant for pizza.



  • 2 large onions, thinly sliced (6 cups)
  • 2 Tbs. olive oil
  • 1 tsp. dried thyme, crushed
  • 1/2 tsp. ground black pepper
  • 2tsp. balsamic vinegar
  • 1 16-oz. pkg. ready-to-bake pizza dough, such as Trader Joe's
  • 1 cup grated part-skim mozzarella cheese
  • 1/2 cup grated aged provolone cheese
  • 20 nicoise or 10 kalamata olives, pitted and halved (2 Tbs.)


1. Heat oil in skillet over medium heat. Add onions, and sprinkle with salt, if desired. Sauté 5 to 7 minutes, or until softened. Reduce heat to medium-low, and stir in thyme and black pepper. Cook 15 minutes more, or until onions are browned and caramelized, stirring often. Stir in vinegar, and cook 5 minutes more. Remove from heat.

2. Preheat oven to 425°F. Coat 12-inch pizza pan or rectangular baking sheet with cooking spray. Press dough into 10-inch circle on pizza pan or baking sheet. Sprinkle 1/2 cup mozzarella and 1/4 cup provolone over dough. Spread onions over top, then sprinkle with remaining cheese and olives. Bake 20 minutes, or until crust is golden.
