Bacon and Blue Cheese Tart

I made this for my book club last Sunday and it was super yum.  I adapted the recipe from the March Woman's Day magazine. 

Ingredients:
7 slices turkey bacon
1 large vidalia onion, thinly sliced
1 sheet frozen puff pastry, thawed
2 oz blue cheese crumbled*

Directions:
Heat oven to 400 and line a baking sheet with parchment paper.  Cook bacon in skillet until crisp, move to paper towel-lined plate.  Crumble when cool.  Cook onions in bacon grease (there won't be much, this is turkey bacon)  until very tender and carmelized. Stir bacon back into skillet with pepper to taste. 

Place pastry flat on baking sheet.  Top with onion and bacon, then the blue cheese, leaving a border around the edge.  Bake until pastry is golden, around 25 minutes. Serve warm or at room temperature.  (Matt was eating it cold out of the fridge.)

*There is a huge price difference in the blue cheese sold in the cheese section in the deli of the grocery store and the blue cheese in the dairy case with the sliced and shredded cheeses.  The blue cheese is the dairy case is significantly cheaper.
