Preparation

Step 1

Heat oil in heavy large skillet over medium heat. Add onions and saute until deep golden brown, about 30 minutes. Mix in thyme. Season to taste with salt and pepper. Cool. (Can be prepared 1 day ahead. Cover and refrigerate).

Roll out pastry on lightly floured work surface to 12" square. Cut pastry lengthwise into six 2-inch-wide strips. Cut strips crosswise into 2-inch squares for a total of 36 squares. Place pastry squares,spacing apart, on 2 large baking sheets. (Can be prepared 1 day ahead. Cover and refrigerate).

Preheat oven to 350 degrees. Spoon 1 1/2 teaspoons onion mixture atop each pastry square. Top with 2 apple slices. Bake until pastry is golden brown, about 20 minutes. Top each with 1 piece of cheese and bake just until cheese melts, about 3 minutes.
