Goat Cheese & Caramelized Onion Tarts

Start by slicing 1 large yellow onion (use 2 onions if you are doing both sheets of puff pastry). In a skillet, add 3 tablespoons of olive oil and 1 tablespoon of butter. Add the sliced onions and cook for about 30-35 minutes until caramelized. Remove from heat and add a splash of balsamic vinegar and a sprig of fresh thyme. Preheat oven to 400°F (or whatever the puff pastry package instructions say). Slice thawed puff pastry into bite-sized squares; one sheet should give you about 12 squares. Add the caramelized onions to the middle of each square, leaving a little border on the edges. Add crumbled goat cheese to the top of each tart. Bake for 20 minutes until the pastry is puffed and golden. Optionally, drizzle with honey, sprinkle with sea salt, and garnish with fresh thyme.
