# 2 large Vidaliaonions, thinly sliced (6 cups)
# 2 Tbs. olive oil
# 1 tsp. dried thyme, crushed
# 1/2 tsp. ground black pepper
# 2 tsp. 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
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. Bake 20 minutes, or until crust is golden.
Very worthwhile. Will make again
