Pie or unflavored pizza dough
Goat cheese spread:
For the tarts: Preheat oven to 350°F. On a floured surface, roll out pie or pizza dough 1/8-inch thick. Cut dough into 15 (4-inch) circles. Pierce dough randomly with a fork. Brush lightly with olive oil. Bake for 5-7 minutes, until golden brown and crisp. Remove from oven and cool.
For the goat cheese spread: Combine all spread ingredients.
For the caramelized onions: Heat olive oil in a large skillet over low heat. Add onions and cook until translucent. Add garlic, salt, pepper and sugar; cook for about 10-15 minutes, until onions are dark brown and sweet. Stir in parsley. Remove from heat and cool.
To assemble: Spread some goat cheese mixture over each crust. Spread caramelized onions over goat cheese. Bake for 5-7 minutes. Serve immediately and enjoy.
