Apple Onion Tart

This is a little bit on the unusual side and you may be hesitant to try it :)  This is kind of a hit or miss recipe.  Some people LOVE it and others can leave it.  I personally like the unusual combo of apple, onion, cheese, and bacon.  You can make mini ones, or family style as pictured above.

Ingredients 

1 cup (4 oz.) shredded Asiago cheese, divided 

2 tablespoons butter 

1 3/4 cups diced sweet onion 

1 3/4 cups peeled and diced Granny Smith apples (about 2 large) 

1 tablespoon light brown sugar 

1 tablespoon balsamic vinegar 

1/2 teaspoon freshly ground black pepper 

1/2 teaspoon table salt 

2 teaspoons dried thyme 

4 bacon slices, cooked and finely chopped

1 Package Puff Pastry

Preparation 

1. Melt 2 Tbsp. butter in a medium skillet over medium heat; add onion and brown sugar, and sauté 5 minutes. Add apple and vinegar, pepper, salt, and thyme, and cook, stirring occasionally, 10 minutes or until golden brown. Remove from heat, and cool completely.

2. Preheat oven to 400. Roll out puff pastry and cut each square of pastry into 3rds making six rectangles.  Lay rectangles on a 111x 17 baking sheets lined with parchment.  Spoon apple onion mixture then Sprinkle bacon and cheese on top.

4. Bake at 400 for 20  minutes or until edges of puff pastry are golden brown. Remove from pan to a wire rack and cut into desired size after it has cooled.  Serve warm or at room temperature.
